  Peter Higgs - Wikipedia, the free encyclopedia
Higgs is best known for his 1960s proposal of broken symmetry in electroweak theory, explaining the origin of mass of elementary particles in general and of the W and Z bosons in particular.
This so-called Higgs mechanism predicts the existence of a new particle, the Higgs boson.
Peter Higgs has been awarded a number of prizes in recognition of his work, including the Dirac Medal and Prize for outstanding contributions to theoretical physics from the Institute of Physics, the 1997 High Energy and Particle Physics Prize by the European Physical Society, and the 2004 Wolf Prize in Physics.

 Open Questions: Higgs Physics
Since the Higgs particle generates the mass of all other particles that couple to it, their mass would depend on their orientation with respect to the Higgs field.) Hence the Higgs particle is a boson, a "scalar" boson, since having spin 0 means that it behaves like a scalar under Lorentz transformations.
Recall that a basic postulate about the Higgs field was that when the energy of the field is plotted against the strength of the field, the resulting graph has a W shape.
The Higgs mechanism provides a means of explaining the masses of particles, through their coupling with the Higgs field, without sacrificing mathematical consistency of the standard model.

 Higgs
This mechanism introduces a new particle: the Higgs boson, where "boson" indicates that the intrinsic spin of the particle is an integer; in fact, the spin turns out to be precisely 0, so that often the Higgs is also called the Higgs "scalar", instead of boson.
So although the particle itself is massless, interaction with the Higgs field makes it behave as if it had mass (this is, by the way, how the problem with the W bosons mentioned earlier gets solved).
This energy would disturb the continuous Higgs field, and would generate waves (it is a bit like throwing a stone in a lake, to turn the flat surface into a sequence of waves).

 Origins: CERN: Ideas: The Higgs Boson
This clustering effect is the Higgs mechanism, postulated by British physicist Peter Higgs in the 1960s.

Peter Higgs of Edinburgh University then found a solution, but the cost was to introduce a new 'field', filling all of space, which interacts with particles to slow them down and give them a mass, rather like a spoon feels heavier when it is pulled through treacle.

 New Scientist: Hunting the higgs   (Site not responding. Last check: 2007-10-30)
The Higgs particle is the quantum of a new field called the Higgs field, which was zero in the very early Universe, but turned on as the expanding Universe cooled-just as the motion of the Earth emerged when it condensed out of the dust and gas surrounding the early Sun.
Thus the motivation for proving the existence of Higgs particles is as strong or stronger than ever, and there is very good indirect evidence, and a hint of direct evidence, that they do in fact exist.
The LHC will cover the whole range of Higgs particle masses up to 200 GeV and far beyond, and should find the Higgs particle, or whatever does the job that it is supposed to do, whether it's the standard model theory of the Higgs particle that proves to be correct or one of its competitors.
