Higgs mechanism

The mechanism by which the W boson and the Z boson and, more generally, all massive particles, acquire their mass. In the mid 1960s Peter Higgs, and independently Robert Brout and François Englert, predicted the existence of a massive spin-zero particle is now known as the Higgs boson. The Higgs boson is associated with a scalar field, now known as the Higgs field.

In the Weinberg–Salam model the W boson and the Z boson which mediate the weak interaction acquire their masses by the Higgs mechanism. Higgs bosons have not been found experimentally, although thorough searches up to 130 GeV have been conducted. It is thought that fermions in the standard model acquire their masses by the Higgs mechanism but it has not been possible to implement this suggestion.

Higgs mechanism

[′higz ‚mek·ə‚niz·əm]
(particle physics)
The feature of the spontaneously broken gage symmetries that the Goldstone bosons do not appear as physical particles, but instead constitute the zero helicity states of gage vector bosons of nonzero mass (such as the intermediate vector boson).
(quantum mechanics)
A mathematical procedure in which particles in a field theory gain or lose mass due to spontaneous breakdown of symmetry.

We have this target scale, the weak energy scale that the LHC is exploring--that is to say, the scale at which we know particles are somehow acquiring mass associated with the Higgs mechanism.
There is a connection between these two where the origin of mass is explained by a mechanism called the Higgs mechanism. Our primary scientific goal is to find the Higgs."
Some topics under investigation include quantization of field theory on the light front, nonperturbative calculational methods in quantum field theory, massive gauge field theory without Higgs mechanism II, and gauge field theories on noncommutative spaces.
