God Particle
The Higgs boson, sometimes called the Higgs particle, is an elementary particle in the Standard Model of particle physics produced by the excited state, quantum excitation of the Higgs field, one of the field (physics), fields in particle physics theory. In the Standard Model, the Higgs particle is a massive scalar boson with zero spin (physics), spin, even (positive) Parity (physics), parity, no electric charge, and no color charge, colour charge, that Coupling (physics), couples to (interacts with) mass. It is also very unstable, particle decay, decaying into other particles almost immediately. The Higgs field is a scalar field, scalar field (physics), field, with two neutral and two electrically charged components that form a complex doublet (physics), doublet of the weak isospin SU(2) symmetry. Its "Spontaneous symmetry breaking#Mexican hat potential, Mexican hat-shaped" potential leads it to take a nonzero value ''everywhere'' (including otherwise empty space), which ...

Particle Collision
In particle physics, an event refers to the results just after a fundamental interaction takes place between subatomic particles, occurring in a very short time span, at a well-localized region of space. Because of the uncertainty principle, an event in particle physics does not have quite the same meaning as it does in the theory of relativity, in which an "event" is a point in spacetime which can be known exactly, i.e., a spacetime coordinate. Overview In a typical particle physics event, the incoming particles are scattered or destroyed, and up to hundreds of particles can be produced, although few are likely to be new particles not discovered before. In the old bubble chambers and cloud chambers, "events" could be seen by observing charged particle tracks emerging from the region of the event before they curl due to the magnetic field through the chamber acting on the particles. At modern particle accelerators, events are the result of the interactions which occur from a beam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
