gauge boson

n
(Nuclear Physics) physics a boson that mediates the interaction between elementary particles. There are several types: photons for electromagnetic interactions, W and Z intermediate vector bosons for weak interactions, and gravitons for gravitational interactions

An [a.sub.LR]-type interaction can arise at the tree level in models containing a new charged gauge boson with right-handed couplings to the quarks (as in left-right symmetric models), in the SM model if it is extended to contain new heavy "exotic" quarks which have right-handed couplings to the W and which mix with the known quarks, and in models with leptoquarks.
There is also a term involving the doubly charged gauge boson, but it is not relevant for our reasoning [40].
The Higgs VEV generates the B-L gauge boson mass as well as Majorana masses of the right-handed neutrinos.
Under the conformal rescaling (15), other parameters of the Standard Model are unchanged (including gauge boson masses), and in the perturbative analysis on the static background the modification of the vacuum expectation value (18) leads to the alteration of the parameter (2),
Derivation of gauge boson masses from the dynamics of Levy flows.
The interaction between a spin-1/2 excited lepton, a gauge boson (V = y, Z, [W.sup.[+ or -]] , and the SM leptons is described by SU(2) x U(1) invariant Lagrangian [4,27,28] as
At extremely conditions, the gauge boson force field undergoes a quantum space phase transition to a "hedge boson force field", consisting of a "vacuum" core surrounded by a hedge boson shell, like a bubble with boundary.
In this work, we consider the dimension-6 CP-conserving interactions of the Higgs boson and electroweak gauge boson in SILH basis as [34]
The Weak and the Strong geometric coupling constant strength, defined as the probability for a particle to emit and later absorb a SU(2), SU(3) gauge boson, can both be obtained by using the main formula derived from Geometric Probability (as ratios of dimensionless measures/volumes) after one identifies the suitable homogeneous domains and their Shilov boundaries to work with.
It is interesting to note that despite three Higgs representations [5.sub.H], [24.sub.H], [75.sub.H], major contribution to threshold uncertainty in the model is only due to superheavy gauge bosons. When all superheavy gauge boson masses are identically equal to [M.sub.U], superheavy scalar mass splitting by a factor 20(1/20) from the GUT scale gives [[eta].sub.S] = 1.3(-1.3) leading to [[[[tau].sub.p]].sub.max] = 1.80x[10.sup.34] yrs.
