gauge boson

[′gāj ‚bō‚sän]
(physics)
A massless spin-1 particle, such as the photon and gluons, whose existence is required by gauge invariance in a gauge theory; such particles can acquire mass through spontaneous symmetry breaking, as in the case of intermediate vector bosons. Also known as gauge particle.

Moreover, since the W' mass is directly connected to the scale of symmetry breaking of the model, a lower mass bound on the gauge boson represents also a lower bound on the scale of symmetry breaking.

We have investigated the CP-conserving dimension-6 operators of Higgs boson with other SM gauge bosons via [e.sup.+][e.sup.-] [right arrow] [nu][bar.[nu]]H process using an effective Lagrangian approach at first energy stage of CLIC ([square root of s] = 380 GeV, [L.sub.int] = 500 [fb.sup.-1]).

The only SU(2) triplet DM candidate in the MSSM is the wino-like neutralino, dominated by the fermionic superpartner of the [W.sub.3] weak gauge boson. The wino belongs to the adjoint representation of the gauge group (hypercharge Y = 0) and the wino-like neutralino emerges, after EWSB, from the diagonalization of (1) in the limit [absolute value of ([M.sub.2])] [much less than] [M.sub.1], [mu].
The gauge boson coupling to Higgs and [eta] (the equivalent of (4)) will be (neglecting hypercharge)
The hidden sector is coupled to the standard model (SM) via the "Higgs-portal" mechanism due to the [phi] mixing with the SM Higgs boson h and also via the loop-level couplings of [phi] to two gluons and [phi] to two hypercharge gauge bosons induced by U.
The first one is that the [s.sub.[beta]-[alpha]] factor in the lightest Higgs-gauge coupling is set to unity while the heavier Higgs, H, decouples from gauge bosons [16].
We consider an EFT approach where a heavy scalar [PHI] interacts with the SM gauge bosons through the dimension-5 operators and with the SM quarks through the dimension-4 operators.
