EPTHiggs is not what gives you, as a person, mass. The Higgs boson give the fundamental particles mass. Analogy: a room of journalists uniformly distributed through the room. An unknown person passes through and doesn't attract any attention. A famous person attracts a lot of journalists which makes that famous person slow down.

We will try to get as much data for these measurements before we stop for maintenance. 'A machine that has been working for 3 years needs some maintenance.' Science: Before the LHC turned on, Supersymmetry would come first and the Higgs would come next. Did the Higgs come faster than expected? Yes. The capabilities of the detectors, analysis techniques have proven to be more effective than planned for. As for Supersymmetry We have narrowed down the areas to look and will continue to look. | ||

When the SM was first conceived, not all particles predicted by it had been observed yet. Over the years, most particles in the SM have been found and the predictions of the SM were tested very thoroughly. Until recently, a single particle had not been observed in experiments. This particle, the Higgs boson, was part of a mechanism (the Higgs mechanism) that is responsible for the differences in mass between all the other particles. The SM predicts many of its properties, except for its mass. In the Large Hadron Collider (LHC), protons have been collided at extremely high energies. Due to the equivalence of energy and mass (the famous e=mc^2 equation), high energies can give rise to the production of massive particles. With millions of collisions per second, the detectors at LHC gathered enormous amounts of data. The presentations today showed that a new particle was found with the properties that were predicted for the Higgs boson. Hints that the Higgs boson existed already came out last year, but the statistical uncertainties were still too large to claim a discovery (~3% chance that the signal was due to random luck). With additional data-taking and more efficient analysis, the researches can now conclusively say that they have found a new particle and that its properties, so far, line up with what was expected of the Higgs boson. The Higgs boson is the last of the predicted particles of the SM to be discovered, so in a sense, the theory is now complete. It's not the end of the search though, because for all its successes, the SM doesn't answer all questions. There has to be additional physics to explain some observations, possibly through new particles. One of the main open questions is the Dark Matter problem: The amount of observed mass in the universe is not nearly enough to explain the motion of galaxies. The largest part of the matter in the universe is expected to consist of particles that we don't know yet. Very nicely put and greatly appreciated! | ||

A famous person attracts a lot of journalists which makes that famous person slow down. I'm confused by your analogy. If a fundamental particle attracts higgs bosons to get mass, why is it that we haven't found any? From what I know of particle physics, the general problem with finding particles is that they are created at extreme energy levels, which is why we build bigger and better particle accelerators. Now, if a particle is needed to "give" mass, why isn't our world completely filled by it? | ||

If 1 particle collision is a particle of sand, then all of the collisions together would fill an olympic sized swimming pool. What else does LHC do other than the Higgs? For the rest of the year, we will continue to search and see what else we find. | ||

The question should go to the Nobel prize committee. This was an amazing result. | ||

Great random example from the press conference: If you'd fill an olympic sized swimming pool full of sand, each sandcorn would represent a single proton collusion in the LHC. Out of those a few dozen were significant for the results presented today. | ||

Now, if a particle is needed to "give" mass, why isn't our world completely filled by it? Particles get their mass from an energy field, the Higgs field. Due to the theory of quantum field theory, there's an equivalence between energy fields and particles. Particles represent the fields and fields can be considered a continuum description of particles. Compare this with photons (particles) and electromagnetic waves (fields), which are 2 sides of the same coin. The Higgs field permeates the entire universe. The Higgs boson, on the other hand, is an unstable particle that is linked to this field. To measure the field, we need to measure the particle. The particle is massive and hard to find, which explains why we don't see it easily. It's a bit hard to explain this as quantum field theory is an extremely abstract field of science, but I hope this sheds a light on it. | ||

The LHC will operate at 4 TeV per beam until the end of 2012, 0.5 TeV higher than in 2010 and 2011. It will then go into shutdown for 20 months for upgrades to allow full energy operation (7 TeV per beam), with reopening planned for late 2014. (wiki) | ||
