Large Hadron Collider smashes another record

"This is now 100 million collisions per second," Spiro said at a conference in Paris on the "infinitely small and the infinitely big."
Among the puzzles that physicists are seeking to answer is the existence of the Higgs, which has been dubbed "the God particle" for being mysterious yet ubiquitous.

When you do most things 100 million times without results...at least the results your looking for, most people quit.

Isn't this the definition of insanity? Doing it over and over, expecting different results?

Sounds eerily like "Hey let's just build this tower taller so we can reach heaven..."

It would be nice to have a link to the video discussed in the article.

Please respond with scientific criticism. This is a science forum. I understand you have no idea what the article is about, but your criticisms are not rational.

This is actually a science news webpage with a comment section.

Which I'm free to comment freely on. My criticism does not have to be "science" related. It can be journalism related or even simply logically related.

For this article, I'm merely asking at what point do they quit chasing it or try something else, because so far, the more than trillions of collisions haven't produced the Higgs.

At what point do we declare it's a dead horse or stop beating it? I think that's a valid question.

There are some very intelligent people who, over the course of our civilization, have built some very reliable and also complex statistical models for how to determine when data is significant, and when it's just background noise. The trillions of collisions produced thus far have not yet ruled the Higgs particle as "definitely there" nor "definitely not there" by these rigorous statistical standards. Have confidence that when they announce that the Higgs either does exist or doesn't, the annoucement will have the full agreement of these statistical models behind them.

Now see, Nano offers a very polite, well reasoned reply. Take notes Nerd so you can graduate to a "Full"Nerd.

Another way to think of it: if a Higgs Boson only appears once in every trillion trillion proton collisions, that doesn't mean it doesn't exist, it just means it's very, very difficult to produce. 100 million collisions sounds like a lot, but it's important to remember that numers we think of as huge (things like 'a billion' or 'a trillion'), are not so huge at the atomic and subatomic levels. To give you an idea, an 8 ounce glass of water has about 8 trillion trillion (8x10^24) molecules of water in it. You can drink that in just a few seconds. 100 million proton collisions by comparison seems pretty puny, despite it being a new record. It's tough to comprehend the scales, both large and small, that this kind of research exists on.

That is the WORST definition of insanity and I hate it. I've met many dozens of schizophrenics and none of them do this. Ever. You just defined /stupidity/, not insanity. I don't know who came up with that retarded definition (pun intended) but they were stupid; as is the act of repeating things without thinking first.

Sorry, I ain't madatcha, Yellow; just using your comment to vent. If the LHC really was doing the same thing repeatedly, for no good reason (they aren't), then they would be stupid, not insane.

/rant

Just curious: Why was your question framed that way instead of framing it like a question from ignorance. It's as if you assumed experienced physicists are either stupid or crazy instead of assuming you just didn't have all the facts. I would have merely asked, "why do they need so many attempts?"

What is likely to happen is that even if they find something that explains mass, there will probably be some discrepancy which will then need to be explained by yet another "fundamental" particle, ad nauseum.

It's a good thing that the Curies kept on trying until they were able to isolate 1 gram of radium salts from 7 tons of pitchblende, eh? That's 1 part in 7 million rather than 100 million, but you get the point, I hope. They could tell that *something* was there, even though it was heart- (and back-)breakingly difficult to reach. Similarly (say I), the Higgs searchers believe that *something* is there, at the bottom of that mysterious property called mass, but that it will be quite difficult to properly detect.

@spectator

"Probably"? What is your estimate of this probability, please? (Upon what do you base this dismissal?)

Also heard that he wasn't a psychiatrist? Try again. Einstein was also a quote machine, not Webster.

Einstein was a genius, but no expert on insanity. In my decidedly unprofessional opinion, doing the same thing again and again and expecting a new result is merely one possible manifestation of insanity and not the definition of said condition.

Furthermore, the article clearly states that only a portion of the protons in the collider actually collide. If
some of the protons are not involved in collisions, it is reasonable to assume that the angle of incidence
in each collision is unpredictible. I base this assumption on the fact that the results of each and every
collision are not identical to each and every other collision. If the results of each collision are unique
and unpredictable, then are they really doing the same thing over and over? I would have to say no.

Yellowdart based their comment on some that was NOT happening each time without giving consideration to what actually WAS happening each time.
But what do I know? I'm just a construction worker.

"Probably"? What is your estimate of this probability, please? (Upon what do you base this dismissal?)

Obviously the fact that in the past each time a new particle was discovered it never quite answered anything, and ended up requiring yet another particle or force to explain the discrepancy.

Same pattern; why would it change now?

To all the comments above, I like to masturbate too.

Perhaps PhysOrg could set an example for the scientific media at large, & dispense with any further references to Leon Lederman's 20yr-old attempt to sell his book, via the moniker, `the god particle'. Religion is utterly irrelevant to scientific discovery, & makes a sham of all scientific inquiry and journalism. Let's can the `god particle' moniker once & for all ! It has NOTHING to do with `god' !!!

It's even worse than that. By associating the Higgs with god it implies that the Higgs isn't real (like god), whereas there is credible evidence for the Higgs mechanism and method for its detection.

Yellowdart

In case you may have missed this in the article.

"It had been due to shut down in early 2012 for work enabling it to crank up to full power. But a decision was made several weeks ago to delay closure for a year to help the Higgs hunt."

My understanding would be that these collisions are extremely fast and the LHC uses several instrument packages to study the collisions. The more collisions they have the more data they can collect to verify the results match the models predictions.

After the LHC is shutdown again for maintenance it will begin operating at higher energy levels until it gets to 7 TeV for combined 14 TeV collisions. Since the LHC will be operating at energy levels previously not reached it is reasonable to conclude that new physics may be discovered. Or more interestingly existing theories proven wrong. Either way we should discover another piece of the puzzle.

Regarding insanity "definition" - is then quantum mechanics insane? :P

The first observation of the W bosons was due to 5 particular events out of many months of running the experiment (UA1, Cern) with 10,000 collisions per second. Similar numbers apply to the discovery of the Z boson.

It really drives me crazy how many times I've read the "definition of crazy" on these forums. That being said, I think its very cool that they can definitively say whether or not the particle exists in a year; pretty sweet deductive skills.

This is the best comment I have read so far on encouraging scientific endeavour.

First, on the luminosity issue. The detectors can't record all collisions. There are complex triggers built into the detector. Part of searching for the Higgs is tuning these triggers to look for the Higgs at masses in the predicted range. If you are looking at one in a million collisions, or one in a billion, improved luminosity increases the speed at which they can rule out specific masses for the Higgs.

If they do find the Higgs soon, then it is likely that the detectors at Fermilab--if it is still running, will be able to confirm it. Once you know what you are looking for it is a lot easier to find it.

Second, on "new physics." There have been many times in the past century when the particle zoo was thought to be complete, then a particle outside the standard model, or more often some experiment that required a new particle or new family of particles started the hunt over again.

Right now dark matter needs to be explained, and it has to be outside the standard model.

Regarding insanity "definition" - is then quantum mechanics insane? :P

well if your experiment isn't precise enough you could do something a whole lot of time in QM and get wildly different results -- its a feat to get anything boiled down to jsut a range in that field

At what point do we declare it's a dead horse or stop beating it? I think that's a valid question.

it would be a valid question if all particles appeared with the same energy, at the same ratio as all other particles. Your comment shows a clear lack of understanding of the underlying fundamentals.

Basically:
1. They need to have energy levels high enough to even produce the higgs by itself.
2. The higgs, if it is there, will only appear a very small percentage of the time, even for collisions that are at the right energy.
3. Sorting through billions or trillions of collisions takes a lot of computational power.
4. They need to replicate the results with enough reliability before they can be sure.

And trust me, this is a very very light scratching of the surface.

Regarding insanity "definition" - is then quantum mechanics insane? :P

Is this a trick question? Sometimes quantum mechanics makes me want to go insane. It's probably much easier for schizophrenics to pick up.

@spectator - Finding the higgs is unlikely to ad other missing particles. It is theorized to fill a spot in the standard model...there are a handful of spots unfilled, but I think they have a pretty good handle on what they're looking for.

Einstein was a genius, but no expert on insanity. In my decidedly unprofessional opinion, doing the same thing again and again and expecting a new result is merely one possible manifestation of insanity and not the definition of said condition. The fact that the results of each and every
collision are not identical to each and every other collision...are unique and unpredictable, then are they really doing the same thing over and over? I would have to say no.

Sir, you may be "just a construction worker" but you obviously have either a good education/understanding of quantum mechanics or else remarkably sharp intuitive grasp of the basics of this discipline. Either way, you have nailed one very important aspect of these expirments: quantum uncertainty plays an extremely important roles in experiments involving atomic (and sub-atomic) particles than most would realize. Combine that with the expected very low density of these particles and even 100mil is small qty of test runs

We have learned that Higgs particle was born from Higgs field. Is the Higgs field the same thing as the old aether?

Is the Higgs field the same thing as the old aether?

In certain sense yes. Neither Higgs mechanism, neither old aether were exactly defined.

The search for Higgs is analogous to attempts for detection of presence of water particles with clashing of water surface ripples. It's not just problem of sensitivity, but conceptual problem: you cannot detect/observe the existence of underwater with surface waves, because just this underwater serves as an environment for surface wave spreading. The same object cannot serve as both as subject, both mean of observation.

We should really try and smash some other "stuff" together . The "higgs" particle IS present in any and all matter at all times , so wy is it that hard to pin point it ? The solution obviously lies in the human "soul" , rather then in "one proton"(or several billion millions of aether) .

Except when you've spent enough money on it to fund a small country for a year!

The Higgs boson is a fudge factor for the standard model predicated upon the idea that (quantum) gravity only is responsible for the existence of the universe.

Since that assumption could well be false, it is quite possible that the Higgs will not be found, effectively ending the standard model.

AMEN to that!
The idea that the Higgs is ubiquitous and mysterious does link it to some aspects associated with God. Fine, it's a fair conceit. But the media loves to run away with that sort of thing, and now the expression "The God Particle" is blown way out of proportion.
Please Physorg, Let's not encourage the practice.

"At what point do we declare it's a dead horse or stop beating it? I think that's a valid question."

And it's answered in the article: "If we're lucky, and it (the Higgs) is in the right zone for expected mass, we may be able to find it this summer," he said. "On the other hand, ruling it out will take us to the end of next year."

Please read the article before starting a flame war.

100 million collisions sounds like a lot, but it's important to remember that numers we think of as huge (things like 'a billion' or 'a trillion'), are not so huge at the atomic and subatomic levels. To give you an idea, an 8 ounce glass of water has about 8 trillion trillion (8x10^24)
molecules of water in it.

I deal with ppb and ppm and ppt all the time. Your still doing COLLISIONS at 100 mil/s which times 3600 is 360 bil/hr. So as someone else posted, the computational speed is the bottleneck. I understand that.

But as Baseline points out:

After the LHC is shutdown again for maintenance it will begin operating at higher energy levels until it gets to 7 TeV for combined 14 TeV collisions.

If the energy level is being shown to be inefficient as they've had no detections, much less 15, I see no point in delaying bumping it up to full power.

Furthermore, the article clearly states that only a portion of the protons in the collider actually collide.

And the article clearly states 100 million collisions/second. Not 100 mil particles/second in the system.

Your comment shows a clear lack of understanding of the underlying fundamentals.

Basically:
1. They need to have energy levels high enough to even produce the higgs by itself.
2. The higgs, if it is there, will only appear a very small percentage of the time, even for collisions that are at the right energy.
3. Sorting through billions or trillions of collisions takes a lot of computational power.
4. They need to replicate the results with enough reliability before they can be sure.

Either 1 isn't enough, or 2 lacks the capability to detect. As if I understand it correctly, the more appropriate way to phrase #2 is not that it doesn't appear, but that it isn't detected or doesn't appear to our instruments. Upgrading sounds the way to go either way.
Although, sounds like if our detection sucks, then upgrading to the higher energy level may also be useless until #2 is addressed.

@Dan,

I did. What part of "lucky" do you appreciate when either the energy level is wrong or detection ability has been incapable?

Let me put this in perspective. Over the last year at 100mil/s that equates to a total of 3,153,600,000,000,000 collisions...(if you prefer the 10mil/s it's just an order of magnitude). So your Higgs is currently 0 fer 3,153,600,000,000,000.
