	Higgs boson - Wikipedia, the free encyclopedia
		The Higgs boson is a hypothetical massive scalar elementary particle predicted to exist by the Standard Model of particle physics.
		The Higgs boson was first predicted in 1964 by the British physicist Peter Higgs, working from the ideas of Philip Anderson, and independently by others.
		The particle called Higgs boson is in fact the quantum of one of the components of a Higgs field.

	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.
		Higgs conceived of the mechanism in 1964 while walking the Cairngorms, and returned to his lab declaring he had had his "one big idea".

	Higgs boson
		Higgs bosons are hypothetical elementary particles predicted by the Standard Model of particle physics.
		These bosons play a rather fundamental role: they are the carrier particles of the Higgs field which is thought to permeate the universe and to give mass to all particles.
		The Higgs boson, sometimes called the God particle, was first predicted in the 1960s by the Scottish physicist Peter Higgs[?].

	Higgs-Gluon Theory, a unifying new model. (Site not responding. Last check: 2007-10-21)
		Higgs Boson are primordial particles, individually too small to detect, and are attracted to color charges in Quarks.
		The role of primordial Higgs Boson may be a missing key to understanding the formation of matter at the center of this process.
		Higg's Boson (in all states) propogates and is attracted by Gravity.

	Open Questions: Higgs Physics
		For one thing, the gauge bosons of the theory -- the W and Z particles which mediate the weak force -- have large masses, unlike the gauge bosons of electromagnetism (photons) or of the strong force (gluons).
		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.
		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.

	The Higgs Boson (Site not responding. Last check: 2007-10-21)
		All the known forces in the universe are manifestations of four fundamental forces, the strong, electromagnetic, weak, and gravitational forces.
		Now, since the discovery of the top quark, there is tantalizing evidence that the Higgs boson may have energies in the range of a few hundred GeV and therefore within the range of present day accelerators.
		At Fermilab, data from the D0 detector facility is used with the masses of the W and the T quark to estimate the mass of the Higgs boson.

	Scientific American: What exactly is the Higgs boson? Have physicists proved that it really exists? (Site not responding. Last check: 2007-10-21)
		Discovery of the Higgs boson was one of the principal tasks scheduled for the Superconducting Super Collider, which the U.S. Congress canceled in 1993.
		Supersymmetry entails several Higgs bosons, and one of which probably lies in the energy regime that LEP is starting to survey.
		In the other approach, called dynamical symmetry breaking, the Higgs boson is not an elementary particle but a composite whose properties we may hope to compute once we understand its constituents and their interactions.

	Higgs: the Velcro Boson
		The Higgs boson is an undiscovered elementary particle, thought to be a vital piece of the closely fitting jigsaw of particle physics.
		The Higgs boson’s appendages (hooks and loops) have a directional difference according to the orientation of the particle in the path it is taking.
		All of the other gauge bosons are also equipped with hooks and/or loops that match either the hooks or the loops in the Higgs boson.

	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.
		The question of mass has been an especially puzzling one, and has left the Higgs boson as the single missing piece of the Standard Model yet to be spotted.

	Zeroing in on the Elusive Higgs Boson
		Higgs is the last undiscovered component of the Standard Model, physicists' current theory of matter and the forces of nature.
		The Standard Model predicts a relationship between the masses of the Higgs boson, the W boson (which carries the "weak force"), and a particle called the top quark.
		Precise measurements of the properties of the top quark and W boson at Fermi National Accelerator Laboratory and the Zo at the Stanford Linear Accelerator Center in the 1990s significantly narrowed the predicted range for the mass of the Higgs boson.

	Research News: New Results Change Estimate of Higgs Boson Mass
		In a case of the plot thickening as the mystery unfolds, the Higgs boson has just gotten heavier, even though the subatomic particle has yet to be found.
		Scientists believe that the Higgs boson, named for Scottish physicist Peter Higgs, who first theorized its existence in 1964, is responsible for particle mass, the amount of matter in a particle.
		The Higgs field would be carried by Higgs bosons, just as the electromagnetic field is carried by photons.

	Key sub-atomic particle slips away again - 30 June 2003 - New Scientist
		Higgs particles are difficult to distinguish from background noise, so a high rate of collisions is crucial for a clear signal.
		Although the collider might still be able to show that the Higgs does not exist at 115 GeV, it will almost certainly not be able to disprove the Higgs at higher masses, and will not be able to prove the existence of the particle at any energy.
		If the Higgs is not found at that mass, the LHC should also be powerful enough to scan the rest of the possible masses up to 211 GeV.

		The Higgs boson explains why all other particles have mass and is fundamental to a complete understanding of matter.
		The Higgs boson is thought to be highly unstable and, once produced, should quickly decay.
		Their theory was that all particles acquire their mass through interactions with an all-pervading field, called the Higgs field, which is carried by the Higgs boson.

		The large masses of these bosons, and their observed interactions with known elementary particles, create a curious inconsistency in the mathematical equations that describe the behavior of matter and force.
		In 1964, British physicist Peter Higgs postulated the existence of an invisible field that permeates the universe and is responsible for endowing all matter with mass.
		The Higgs boson exists as both a field and particle, because matter and force exist as both fields and particles, according to Quantum Theory.

	Higgs boson escapes detection by scientists who will continue the chase with new collider
		A long-sought subatomic particle called the Higgs boson has escaped one of the most intense statistical dragnets in the history of science.
		LEP experiments suggest that the Higgs boson has a mass of approximately 115 giga electron volts, which is more than 100 times the mass of a proton.
		If the Higgs boson is still on the loose in 2006, when the LHC is scheduled to begin operation, Oreglia will be looking for it.

	Higgs Boson (Site not responding. Last check: 2007-10-21)
		In the Higgs mechanism, the interaction of a particle with the Higgs field provides the particle's attribute of mass; in my own gravitational theory, the interaction of a particle with the temporal component of spacetime provides the particle's gravitational field, the exact proportional measure and equivalent of mass (Gm).
		Thus the "Higgs" or "metric" field imposes order in terms of allowed metric (dimensional) and particle structure, expressed through the conservation and quantum mechanical laws governing inertial forces and virtual particle-antiparticle pairs; this ordering principle has a single source, the metric structure of spacetime, and a single purpose, the conservation of energy.
		It seems likely that the Higgs field and boson are as superfluous as the "ether" sought by the Michelson-Morley experiment; both may be replaced by Einstein's spacetime metric.

		The theory predicts all the different parameters of the Higgs boson depending on its mass which is the only unknown quantity of the Higgs particle.
		If the mass of the Higgs particle is in the range of 135 to 200 GeV, it will predominantly decay to W boson pairs.
		W bosons cannot be observed directly with the DØ detector, because after their production they decay immediately into other particles.

		The Higgs boson is the particle that 'clings' to objects as they move through the Higgs field which causes a 'drag' that shows up as mass.
		The Higgs boson acquires its mass (or inertial or resistance to change in motion) from 'borrowed' energy.
		IIRC a Higgs scalar field was used to correctly model the W and Z vector bosons.

	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.
		A fit to the LEP and SLC results on Z exchange, as well as the determinations of the W boson and top quark masses from LEP and the Tevatron, predict that the Higgs boson should be lighter than about 220 GeV, with a best fit at around 90 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).

	How Particles Acquire Mass (Site not responding. Last check: 2007-10-21)
		The Higgs boson is a hypothesised particle which, if it exists, would give the mechanism by which particles acquire mass.
		Higgs found that parameters in the equations for the field associated with the particle H can be chosen in such a way that the lowest energy state of that field (empty space) is one with the field not zero.
		If particles no get their masses from interacting with the empty space Higgs field, then the Higgs particle must exist; but we can't be certain without finding the Higgs.
