The Year of the Higgs?
This February, researchers will renew their search for one of the universe's most elusive mysteries, the Higgs boson--a hypothetical particle that if found would give an insight into why particles have certain mass.
The search will take place at the Large Hadron Collider (LHC) at CERN, the world's largest particle accelerator at the European Organization for Nuclear Research in Geneva, Switzerland.
The Higgs boson is the only remaining Standard Model particle that has not been observed in particle physics experiments. But using two separate and complimentary experiments, the A Toroidal LHC Apparatus (ATLAS) and Compact Muon Solenoid (CMS), scientists hope to prove its existence.
Both ATLAS and CMS are particle physics detectors. They are located on opposite sides of the 27-kilometer (17-mile) LHC ring circling the countryside on the outskirts of Geneva, buried deep below ground.
The LHC has been offline during a winter break, which temporarily halted the experiments.
"The research program over this past year was essentially to commission the accelerator and the experiments to make sure that they work and they are giving us sensible results," said physicist Aaron Dominguez of the University of Nebraska and the US CMS experiment, whose work is supported by the National Science Foundation.
The University of Nebraska researchers played an important role in building the LHC detectors and analyzing data that comes from the experiments.
Confident that everything is functioning properly, the LHC research community recently announced a decision to delay a planned shutdown of the particle accelerator until the end of 2012. If the machine continues to function at the current level, researchers believe they can explore the entire "allowed region"--the ranges of mass in which the standard model Higgs boson could exist--by the end of 2012.
"This was one of the reasons to run in 2012 and not just this year," said Gustaaf Brooijmans of Columbia University and the US ATLAS experiment. "Our projections now say that with the 2012 run we should be able to probe about 90-95 percent of the 'allowed region' for the existence of the Higgs boson."
Brooijmans' team at Columbia develops and operates the electronics that read out part of the detector.
"If the accelerator is performing according to plan, we should have a very good first picture of this whole 'allowed range' of the standard model Higgs boson," said Dominguez.

Think of it like a crossword. You have to find the answer using the clue and the words around it. You can't guess just any word simply because it has the right number of letters because then the words around it wont ever quite fit. So, knowing the words around it and the clue to the word itself, physicists guess the answer. You would be right to argue that no answer would ever be 100% right because it is possible that a completely different set of words could fit the puzzle. Possible, but not probable. You can look, but you'll have a hard time ever coming up with a second solution to that solves all of the same problems simultaneously. And, as the complexity of the crossword increases, the probability of finding a second solution decreases.
This is why theories cannot ever be proven true - they can only be proven not false.

Sort of. By design the LHC was built to probe electroweak symmetry breaking. This takes you straight to the Higgs mechanism and, taken together, the origin of mass.
Not finding the Higgs boson would hardly be a waste of time. In fact, finding that there is just one type of Higgs (instead of none or 3, 4, or 5) could be said to be the worst possible outcome. All this would do is trivially complete the last big piece of the Standard Model puzzle without opening the door to a badly needed successor. We know the SM is incomplete because, among other things, it fails to predict-much less explain-Dark Matter and Dark Energy as well as neutrino masses. Just finding the expected Higgs won't help push the theory into any new areas.

No. I figured it out myself. If you look at Hawkings original work here:
http:/prac.us.edu.pl/~ztpce/QM/CMPhawking.pdf
...you'll find he simply doesn't describe this part of the system. He, rather, simply infers that due to the conservation laws, the infalling particle must have negative energy relative to a distant observer. This would only be true of the infalling particle upon separation from the VP pair, but not to the infalling particle/black hole relationship.
It's important to note; even a distant observer will agree there's a GP/KE relationship between the infalling particle and the black hole.
So, the infalling particle subtracts it's negative energy/mass from the black hole, but adds its GP/KE to the black hole.
Voila, matter/energy from nothing (a conservatiion violation).

Nobody denies that the progress of science is one foundation of the progress of societies. No need to enumerate single successes.
The progress of science is the progress of understanding how things work. Observations/measurements lead to falsifiable theories which lead to predictions which lead to new observations and measurements and so on.
Most valuable are not observations which confirm an established theory but observations which might topple established theories.
The falsification of a theory forces scientists to change their model (their understanding how things work).
The change of a physical model opens new opportunities for engineers to invent new technologies.
New technologies bring progress into the idealized global village.

Nothing of the sort. You don't understand Hawking radiation. The black hole is LOSING mass in the form of the virtual particle that escapes...it's essentially evaporating. There is no matter energy creation. The first law of thermodynamics has never been observed to be violated, and any theory that postulates it should be highly suspect.

Obviously, YOU don't understand Hawking Radiation. There's a specific mechanism whereby this "evaporation" supposedly occurs. The problem is, the mechanism as described is incomplete - and when completed, it's a conservation violation.
The infalling particle is a "real particle." Even Hawking says so. It's in his paper which I referenced.
All bodies in motion MUST have relative KE values.

I think I have figured out your mistake but I would to see a confirmation of where you think the imbalance arises. Maybe I found it higher in the thread.
So. The other particle, the one that escapes black hole, has the opposite GP/KE thus the Universe remains balanced.
Also there is the matter of the particle's gravity field which has negative energy equal to the mass-energy of the particles in question. Perhaps this is what you are missing.

Do you see? Even a distant observer will agree that the infalling particle has increasing GP/KE with the BH, whereas the escaping particle's GP/KE with the BH is vanishingly small. they are not opposite and equal anymore (relative to the distant observer).

By that thinking virtual particles are impossible in a gravity field. Yet we have evidence that they exist on Earth. The key would be that the negative energy of the gravity of the particle cancels the positive energy of the mass-energy of the particle.
The way I see it is that since virtual particles CAN exist in a gravity field I don't see the problem. The BH looses energy-mass and the negative energy of the BH's gravity decreases in a manner that is equal to the total energy, both positive and negative, of the escaping particle.

You are fixating in a single virtual pair. Since we know they exist and there is rather a lot of them occurring at all times pretty much anywhere the AVERAGE potential energy of all pairs forming at the Event Horizon is ZERO.
They don't just form on one side of the Hole. This could explain why Dr. Hawking ignored the potential energy. It averages to zero.

Then what the hell is your problem? There IS no problem if there is no potential energy. No PK no reason for it to be in the equations. That isn't the further or further yet. It is the What the Bleep was that part? As you have been complaining about PK all along. No PK no problem but, the on further thought part but not the further yet part, PK IS there when the particles pop into temporary existence. Total KE is zero, at the start, so only initial PK matters. That one I am sure on and I said it before on this.

The further part:
What I said in the previous post isn't true, except for the 'further yet part', from one point of view. There is PK, for virtual particles, WITH MASS, as I made a mistake. Thinking about things in the bathroom does not always cover all the bases. Center oriented vector sets are not always the same as zero, and that is what the PK is, a vector. The potential momentum vector is zero on average. Energy is scalar and NOT a vector and it adds up rather than cancels. So the PK would not be zero. Which is why I don't understand why you just agreed with my MISTAKEN thought that it was zero.
