	Vector boson - Wikipedia, the free encyclopedia
		A vector boson is a boson with spin equal to one unit of
		The most familiar vector boson is the photon, or quantum of light, which is a gauge boson.
		There also exist composite particles that are vector bosons, such as the vector mesons, made of a quark and antiquark with a total angular momentum of one unit.

	Gluon - Wikipedia, the free encyclopedia
		In technical terms, they are vector gauge bosons that mediate strong color charge interactions of quarks in quantum chromodynamics (QCD).
		Vector particles usually have three spin states, but gauge invariance reduces the number of spin states of a gluon to two; negative intrinsic parity, and zero isospin.
		The gluons are vector fields in the adjoint representation (octets, denoted 8) of colour SU(3).

	Higgs boson
		These are all vector (force) fields with their respective quanta: the graviton, the photon, the gluons, the W's and Z. Although the graviton is still not found, its existence can be describe by string theory.
		These are all vector bosons, i.e., force particles.
		The photon, the gluons, all vector boson with no mass, means the Higgs mechanicism does not work on them.

	The Intermediate Vector Boson Hypothesis
		Due to these distinctive characteristics it can immediately be observed that the theory of the intermediate boson of the weak interactions leads to difficulties similar to the ones presented by the model of point interaction.
		It is clear, then, that the renormalization of the theory with intermediate boson based on the Lagrangian (117) is hopeless.
		In other words, the previous discussion indicates that the limit imposed by the unitarity to the cross section of a given process, via the optical theorem, will surely be violated by the massive intermediate vector boson model.

	VECTORS For May 2006 (Site not responding. Last check: 2007-10-30)
		The standard model told the experimental physicists where to look for the vector bosons, and they were finally discovered in 1983 by Carlo Rubbia and his colleagues.
		In contrast to the photon and the gluons, which are spin-1 bosons, the Higgs boson is a spin-0 boson, a fact that gives it distinctive properties.
		The Higgs boson is supposed to be highly interactive with almost everything, and the interactions of Higgs boson (or, equivalently, the Higgs field) with a particle would impede the particle's motion, effectively giving the particle mass.

	Citebase - Vector boson in constant electromagnetic field
		When only electric field is present the Bogoliubov coefficients are independent of boson polarization and are the same as for scalar boson.
		When both electric and magnetic fields are present and collinear, the Bogoliubov coefficients for states with boson spin perpendicular to the field are again the same as in scalar case.
		For gyromagnetic ratio g=2 the vector boson interaction with constant electromagnetic field is described by the functions, which can be expected by comparing wave functions for scalar and Dirac particle in constant electromagnetic field.

	McGraw-Hill AccessScience: Intermediate vector boson
		It is through the exchange of W and Z bosons that two particles interact weakly, just as it is through the exchange of photons that two charged particles interact electromagnetically.
		The intermediate vector bosons were postulated to exist in the 1960s; however, their large masses prevented their production and study at accelerators until 1983.
		Their discovery was a key step toward unification of the weak and electromagnetic interactions.

		We write down a minimal set of genuine four-coupling operators between vector bosons which have no connection to the standard parametrisation of the trilinear anomalous W couplings.
		These requirements are strong enough to forbid or highly suppress any contribution to weak vector boson self-energies.
		We study the effects of these couplings at the NLC (500 GeV) in all possible three vector boson productions: e+ e- arrow W+ W - gamma, ZZ gamma and Z gamma gamma.

		A contact-force representation for the weak part of the field is also derivable from the electroform field equations by a method described by Cottingham and Greenwood, in Introduction to Nuclear Physics.
		Introducing the principle of equivalence as Einstein did in 1911, one imbeds the generalized Maxwellian equations of classical vector boson field theory into a metric with gravitational time-dilation only to describe the forces.
		The falling-ruler thought experiments sometimes used to justify curvature in the spacial part of the metric do not hold for the stationary rulers described by the GR metric, so this book takes the spacial part of the metric to be flat.

		We derive exact expressions for luminosities of massive vector-boson pairs which can be used to describe the cross sections for processes in hadron collisions or{ital e}{sup+}{ital e}{sup{minus}} annihilation which proceed via two-vector-boson scattering.
		Our approach correctly takes into account the mutual influence of the emission of one vector boson on the emission of a second one.
		We show that only approximately the exact luminosities can be factorized into convolutions of single-vector-boson distributions.

		In this working group, we consider topics associated with single W and Z boson production and decay and the possibilities presented with Run II.
		Additionally, with the much higher statistics of Run II, we will be able to consider a triple-differential measurement of the jets and specific jet-tags (charm or bottom).
		The attempt to drive the uncertainty on the W mass to the tens of MeV will likely require further constraints on the production model for vector bosons at low-pT.
