Let's find out.
Precisely measuring the probabilities of these different Higgs decays and comparing the numbers to Standard Model predictions reveal if anything is missing, since the probabilities must add up to one.
After signal-like events have been identified, powerful statistical methods are used to quantify how significant the signal is.
A thorough exploration of the 1-TeV energy scale will determine the mechanism by which the electroweak symmetry is hidden and teach us what makes the W and Z particles massive. The more a particle interacts with this field, the heavier it is.
Higgs boson collider
The existence of the Higgs field became the last unverified part of the Standard Model of particle physics, and for several decades was considered "the central problem in particle physics". But the work didn't come easily. The higher a particle's mass, the more energy it has and the more energy it takes to create that hefty thing. The Higgs boson is the visible manifestation of the Higgs field, rather like a wave at the surface of the sea. The other job of the Higgs boson is to talk to other particles, like electrons; through these conversations, it also gives them mass. The mile loop of super-powered electromagnets can accelerate charged particles to significant fractions of the speed of light, causing collisions violent enough to break these particles into fundamental constituents, and deform space around the impact point. Thus, they can only be studied within a very large number of collisions and using sophisticated analysis techniques. The exact nature of these additional Higgs characters depends on the theory, of course, ranging anywhere from simply one or two extra-heavy Higgs fields to even composite structures made of multiple different kinds of Higgs bosons stuck together.
There was not yet any direct evidence that the Higgs field existed, but even without proof of the field, the accuracy of its predictions led scientists to believe the theory might be true.
But why? But the Higgs that we spotted was surprisingly lightweight.
Detailed simulations showed that there was a chance of discovering the Higgs boson at the reduced energy, in particular in the range where the competition of the Tevatron was the most pressing, so we decided that starting immediately at 7 TeV was worth the chance.
If so, the ball will eventually tunnel to the lower, more stable valley, corresponding to a drop in the energy of the Higgs field.
