Endgame for the Higgs Boson
September 14, 2011 By Susan Brown
A Z boson, possible offspring of a Higgs, further decays into two electrons (green streaks) and two muons (red lines). So far, the scientists aren't convinced that the events they've seen aren't simply blips in background noise. If enough accumulate they'll be confident they've found the Higgs. Image: CERN.
The last missing piece of scientists fundamental model of particle physics is running out of places to hide.
That piece, an elementary particle called the Higgs boson that is thought to give all matter mass, has evaded detection so far. But physicists working at the Large Hadron Collider (LHC) near Geneva, Switzerland, including a contingent of more than two dozen scientists from the University of California, San Diego, have ruled out most of the range of masses the Higgs could have, leaving just a narrow span where the elusive particle might be found.
If it exists, it has to be there. And if its not there, it will be known to be science fiction by December, Vivek Sharma, a physics professor at UC San Diego told Science NOW. Sharma coordinates the international team searching for Higgs boson with the CMS detector, one of two large instruments deployed in the search. The other is called ATLAS.
By speeding protons around a 27 kilometer ring at nearly the speed of light, then smashing them together, scientists fleetingly recreate conditions that prevailed when the universe began. In those moments the Higgs boson, if it exists, should pop into being and then quickly decay into other more familiar and recognizable particles, which CMS and ATLAS are poised to detect.
In just five months of the LHC running, the two teams have eliminated at a 95 percent confidence level most of the range of possible masses the Higgs could have, Sharma reported at the biannual Lepton-Photon conference held recently in Mumbai. The Higgs, if it exists, is now trapped between 114 and 145 GeV (Giga-electron volts, a measure of mass), he said.
A Higgs boson within that range would decay in predictable ways. The scientists have observed the kinds of sprays of particles they would expect to see from a Higgs boson, but not often enough to say the events arent mere statistical fluctuations of well known background processes.
A definitive interpretation will require more data, which the LHC is starting to deliver. Now back in operation after a pause that has allowed the team to ramp up the rate of collisions, the machine should deliver twice as much data as has accumulated so far by the end of October.
We are now entering a very exciting phase in the hunt for the Higgs boson, Sharma said. If the Higgs boson exists between 114-145 GeV, we should start seeing statistically significant excesses over estimated backgrounds, and if it does not then we hope to rule it out over the entire mass range. One way or the other we are poised for a major discovery, likely by the end of this year.

After all, why such background particles should exist at all in completely random Universe? It's observable structures are defined with us, human observers, not with intrinsic structure of Universe. Every fluctuation in it would interact with the fluctuations of the same size and energy density predominantly. Such selection could lead into well distinct masses of elementary particles and stellar objects of various types, but no uniformity actually exists here - it's only human abstraction of observations.

The lightweight elementary quarks are surrounded with Higgs field, which lead into so-called Yukawa coupling and gluing of particles together. The heavier these quarks are, the more the space-time is collapsed around them and the more the Higgs field and the energy of Yukawa coupling becomes pronounced into account of quarks itself. At the case of the heaviest top quarks the mass of quarks is solely composed of their Higgs boson field - in this sense the top-quark pairs are behaving (nearly) like pure Higgs boson pairs.

Energy binds on space time in a way that we do not understand, that't it. Energy does not exist in terms of matter. It is a concept that is useful to get an understanding. But the speed of light and what light is not even understood, so we are not going to fully know energy until we know what causes light speed limitation. Something is binding (energy, vibration, whatever it is), it creates "particules" in some conditions, and this causes a twist in the univers that we see. Maybe the Higgs Boson is doing that, but chances are 1 in a high number of other posibilites. At sub atomic level, the Univers seems to be much more highly related to the laws gouverning space time curvature than it is to the laws of Newton, so the Boson is not even likely. But there is a chance it exists, but as any other theories of unexplained phenomenons, it is just poetry as of today. Why so many physicis stick to this single theory is not rational.

You are confusing the pure application of the scientific method with the politics that influence the funding of scientific investigation.
If the majority of planetary scientists believed there were trees on the far side of pluto then it would be worth investigating.
An idea or theory is not "BS" when it has the backing of the majority of experts in the field to which it pertains.

For example, the studying of low energy nuclear reactions and gravitational waves is the "basic research" in both cases. Under such a situation it would seem logical, the basic research with potential applications will always get some priority.
Whereas my feeling is, when physicists are clueless, then they will always choose the less useful research instinctively. Some guys revealed antigravity beams and/or room temperature superconductivity (which are both things, which are pretty fundamental for every theory of gravity and/or superconductivity) - but no, the rest of physicists will ignore these findings obstinately on behalf of the research of some useless things.
This is apparently waste of tax payers resources. If we want to deal with something really new - why not to choose the research of the usable new things first?

What will surely occur is that theorists will try to imagine bridges from the Higgs to theories which don't involve the Higgs, which involve the least admission of error possible.
What will NOT occur is an admission that there is a fundamental error lurking somewhere in the logic and philosophy which got us here. Nor will there be some humble attempt to question the assumptions which got us here, from a different set of hypotheses.
It is amazing, but we are still repeating Plato's and Socrates' biggest mistake: The scientific method remains a form of *directed* inquiry. The Socratic dialectic was *never* intended to be a form of open-ended inquiry!
The Greeks favored an ideal state over the real, natural state. They favored the thought experiment over the real experiment. They would imagine what the universe *should* be, and then tried to elicit evidence to support that view.

And that would basically take us back to the Dayton-Miller experiment -- at the point where it was being alleged that the aether could behave as a liquid crystalline lattice which drags with the Earth and other large cosmic bodies.
The reason I say this has to do with water. Water is not turning out to be the homogenous liquid that everybody assumed. It has been known for 40 years now that water has an inherent structure. And it appears that water's extraordinary dipolarity leads to unexpected resonant qualities. Water's inherent crystalline structure appears to be the key to life and its origins, and we can refashion much of science from this new starting point. Where you find resonance, you will also find life trying to take advantage of this resonance.
We can probably re-investigate the aether by studying water.

Who is 'we'? Not the scientific community. Striving to understand is the method of science, but its practitioners are well aware of their limits and the limits of ultimate knowledge.
We don't know that as we haven't exhausted the set of all theories. In any case, scientists tend to favor simpler solutions and oftentimes the highly complex reduces to the simple, when new insight is gleaned.
Probably not as we will never actually know if our models reflect the 'actual' nature of reality, though our confidence will be boosted.

Why is it egotistical to want to seek knowledge about the workings of the universe? You would rather be blissfully ignorant and carry on with idle daily pleasures? Has it occurred to you that there are those who actually DO find joy and pleasure in unlocking the secrets of the universe?
Of course they do - they're certainly not it for the big bucks!

Until the string theory is actually unfalsifiable due its huge landscape of 10^500 predictions, indeed...

The physicists should decide, whether they will develop a "theories", which will "survive" all their falsifications - or whether they will develop a theories, which don't allow everything what you want.

IMO it's not accidental coincidence at all - the physicists did the very same trivial mistake at all cases. Try to imagine, you're walking in the landscape under the haze. You can extrapolate the shape of landscape easily from the local terrain - but you cannot expect it anyway, until you don't realize, it will remain hidden inside of fog. It means, the physicists have no feedback about validity scope of their theories - this information doesn't follow directly from existing formal models. The equations will give you a median value, but they will not tell you, how fuzzy and widespread in quantum noise it will be.

His theories both work quite well, if the bug doesn't try to describe his closest neighbouring reality, where both kinds of waves overlap. So he extrapolates his theories farther both into large scales, both smaller scales...

The first memo is, it doesn't matter, how clever you are and how brilliant your theory is: if you extrapolate it from your dimensional/energy density scale too much, it will always get wrong - despite the hypothetical remote observer would see all its predictions clearly. This is what the multiverse concept at the aether model means - the theories are such an abstract multiverses too.

Which is definitely better criterion of truth, but the pioneers of new ideas aren't influential by their very nature, whereas the recognized people tend to remain conservative at times.
Arthur C. Clarke: "If an elderly but distinguished scientist says that something is possible, he is almost certainly right; but if he says that it is impossible, he is very probably wrong."
It means, the recognized people are good advisers in general - but poor critics.

I too have had various posting problems over time. I have had posts that have just vanished into the gloom of the information highway when I tried to submit them. Some have disappeared just from me scrolling back up the page to recheck someone else's information. This editor also won't allow you to use various basic symbols (what a joke!). There is no 'save' option. If the site goes down, you will be submitting to a page that is now off-line. That too can cause problems. When I tried to submit my last post earlier, the submit button was inactive. Here is a little trick that I have learnt:
1. Put mouse pointer into comment box.
2. Right-click. Choose 'select all' to highlight your entire text.
3. Right-click again. Choose 'copy'.
4. If your text has been lost for any reason, right-click back into box. Choose 'paste'
Congrats, you have just used your mouse as a single item virtual save button.
5. To get around inactive submit button, do the above, hit 'refresh', then paste.

In brief, we should always put a question, if our assumption is really unnecessary and if it doesn't actually make our models more complex, than it could be... The modern physicists aren't motivated in such simplification too much, because the more complex theories they develop, the more theorists can keep their jobs. Which is why they're adhering on Big Bang concept so much - it's mystery, which could be analysed - although it may not exist at all

The important thing is that the scientists remain honest to scientific principles and explore every possibility if something strikes them as being strange.
I would also love if whatever it is that they call "random background noise" would be taken much more serious. I hope they find ways to explore if there is matter that is smaller than anything we know.

Thank you for the intelligent, rational and on-topic comments and sanity-checks. The outcome will be a breakthrough - Higgs or no, there will always be more questions. Cool stuff. Some folks don't know just how many modern conveniences (miniaturization in electronics - that tiny cellphone in your pocket) result directly from the study of quantum-mechanics and the like. Even while it "doesn't make sense", contradicting/defying understanding, e.g. non-locality, photon-slit, etc.. Tech companies use these findings continuously (satellite, computer, etc..).
The closed-mind, for it's own sake or conspiracy lust; the guy who's smart, but apparently not self-aware, can't resist sharing his literary brilliance throuh imaginative sci-fi (double-talk, pseudoscience) to pontificate at real scientists about what he can't fully understand.

I was simply thanking a few people who were discussing the process, experimentation and observation in testing theory; attempting to expand understanding, e.g. how a (theoretical) zero-mass fundamental particle (Higgs?) might be coupled with a quantum field (Higgs?) of non-zero vacuum expectation value that's associated to each point of spacetime, causing that particle to acquire mass. I like mass, it makes a pint far more enjoyable. On such a subject I am a layman, sir - but I've read a few "crackpots on the web" myself. No, not you. I do believe that *Data* is far superior to *reason* for supporting one's stance. And again - I have not ranked any post here. But I am skeptical that "nobody cares about it", as you've stated.

That's simply too broad a definition of success.
By that criteria, any endeavor that one undertook could be labeled a success if afterward you could somehow honestly say "Well, we learned something..." whether or not it was what you set out to find.
Failed experiments can be very useful. Failed experiments can provide us with crucial knowledge, even (and especially) from unforeseen quarters. But even doing so doesn't make them successful.
