  Higgs boson - Wikipedia, the free encyclopedia
The Higgs boson is a hypothetical elementary particle predicted to exist by the Standard Model of particle physics.
The Higgs mechanism is a physical phenomenon that is responsible for the spontaneous breaking of the electroweak symmetry.
A technical presentation of spontaneous symmetry breaking and the formation of the Higgs field, in the context of quantum field theory, is given in the article on the Yukawa interaction.

 Joe Higgs: Bob Marley's Musical Influences   (Site not responding. Last check: 2007-10-28)
Having gained from the spiritual aspect of her teaching, Joe Higgs took particular care to play the part of both musical and moral tutor to those youth in the area with the ears to hear.
The musical seminars he conducted could be rigorous affairs: a lot of emphasis would be placed on breath control and melody, and in addition to guitar lessons, he would instruct his students in the art of writing lyrics that could carry clear ideas to the people.
It was in Higg's yard, on one of these occasions, that Nesta had his first encounter with that natural resource with which he was to become associated in the public mind, and which allowed him to empathise with jazz.

 Origins: CERN: Ideas: The Higgs Boson
This clustering effect is the Higgs mechanism, postulated by British physicist Peter Higgs in the 1960s.
The same might be true in the Higgs field: a particle moving through it creates a little bit of distortion -- like the crowd around the star at the party -- and that lends mass to the particle.
In fact, the search for the Higgs particle(s) is some of the most exciting research happening, because it could lead to completely new discoveries in particle 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.

 Marie HIGGS et al. v. ESTATE of Wilton HIGGS
Kinard [appellee's counsel]: Our position is that Herman Higgs was not the primary beneficiary of this will and Herman Higgs has not been shown to have done or caused anything to occur which meets thecriteria of procurement and further there has been no evidence to tend to prove there was undue influence.
Herman Higgs then shouldered the burden of proving by a clear preponderance of the evidence that he took no advantage of his influence with Wilton Higgs and that the testamentary gift made to him was a result of Wilton's own volition.
Higgs proved by a clear preponderance of the evidence the nonexistence of the exercise of undue influence which should have been presumed.

 Joe Higgs: Respect is Overdue
However, in Higgs' case, respect is not only long overdue, but "The Father of Reggae" is worthy of these accolades, not only for his wealth of songs, or his messages, or even for his over 40 year career as an ambassador of consciousness in music.
Higgs did not mean for the lyrics to be one-time teachings, but intended them as a way of passing the torch, instructing others to become teachers themselves and continue to try and better the world.
Higgs provided a voice to the voiceless, championed truth, and transcended above class, race, sex, age, time, and religion, and created music that is still as relevant, crucial, and alive today as the day it was written and recorded.

 CERN Courier - LEP pursues Higgs boson and - IOP Publishing - article
Of the many results presented recently at the EPS conference in Tampere, Finland, and the lepton­photon symposium at Stanford, the search for the Higgs boson and the measurement of the W mass were the highlights.
Based on last year's data, at a collision energy of 189 GeV, the combined lower limit on the Higgs mass from the four LEP experiments was 95.2 GeV.
Via many of the same measurements that are used to constrain the Higgs boson indirectly, the experimenters (with a great deal of help from the theorists) have coaxed the Standard Model into predicting the mass of the W boson with an error of only 26 MeV (in 80 GeV).

 Introducing the little Higgs (November 2002) - Physics World - PhysicsWeb
Higgs and the others - building on earlier work by Julian Schwinger and Phil Anderson - showed how electroweak symmetry could be broken, thus allowing particles to have mass.
The stronger the interactions between the particles and the Higgs condensate are, the heavier the particles become.
Although we have much circumstantial evidence for the Higgs particle, given that fundamental particles have masses that are consistent with the Higgs mechanism and from indirect measurements at CERN and Stanford (so-called precision electroweak data), Higgs particles have never been directly produced and observed in collider experiments.

 The Higgs mechanism   (Site not responding. Last check: 2007-10-28)
In summary, it is seen that a complex scalar field and a massless vector field, both with two degrees of freedom, in (2.20) as a result of the Higgs mechanism was transformed in (2.24) into one real scalar field with one degree of freedom and a massive vector boson field with 3 degrees of freedom.
The massless vector boson is of course to be identified with the photon and the single remaining scalar with the Higgs boson.
While this makes it impossible to put constraints on the Higgs mass and the fermion masses, it has the consequence that the Higgs particle will couple to the fermions in proportion to their mass.

The elusive Higgs boson is so central to the standard model - the theory on which physicists base their whole understanding of matter - that it has been dubbed the "God particle".
But that didn't explain why the particles also have mass, until Peter Higgs at Edinburgh University suggested space is filled with a heavy, treacly substance - now called the Higgs field - which gives particles their mass by dragging on them through a mediator called the Higgs boson.
The problem for physicists is that without the Higgs particle they don't have a viable theory of matter.

 What is a Higgs Particle?
The Higgs particle is as yet a hypothetical particle invoked to explain why the carriers of the electroweak force (the W and Z bosons) have mass.
Quantum electrodynamics requires the photon to have zero mass (which is good because indeed it does), but early attempts to develop and electroweak theory also required the bosons to be massless, (which is bad because then they would be as abundant as the photon in the universe, which indeed they are not).
If there is an otherwise undetectable field filling the universe (now called the Higgs field), it could have associated with it a previously unknown kind of boson, the Higgs particle, which has mass.
