Gauge group physics
WebThe SU (3) color group is the exact gauge symmetry of the Standard Model, which accounts for the strong interactions of quarks and gluons. The theory of the strong interactions is called quantum chromodynamics (QCD). Quarks occur in the fundamental three-dimensional representation of SU (3) color. The three complex components of the … WebQuantum electrodynamics is an abelian gauge theory with the symmetry group U(1) and has one gauge field, the electromagnetic four-potential, with the photon being the gauge boson. The Standard Model is a non …

Webin the gauge group can have serious consequence for the theory (see, e.g., Ref.[2]). If we do not impose any particular boundary conditions so that the boundary conditions are ”free”, G will contain constant functions and the associated global group Gmay be thought of as the subgroup of G of these constant functions. Let G be a gauge ... Web10.5 Precision flavor physics 10.6 Experimental results 10.7 Constraints on new physics 10.1. Introduction The standard model of the electroweak interactions (SM) [1] is based on the gauge group SU(2) × U(1), with gauge bosons Wµi, i= 1,2,3, and Bµ for the SU(2) and U(1) factors, respectively, and the corresponding gauge coupling constants ...
WebJun 11, 2024 · In gauge theory physics, a representation ρ \rho of the gauge group G G encodes the particle-content of the model (in theoretical physics): a section of the ρ \rho-associated bundle to the gauge bundle is a matter field in the model. Therefore all the ingredients so far encode the kinematics of gauge theory, its setup before an actual ... WebYour global gauge group is what physicists call the group of gauge transformations.
