Electroweak interaction as a research area encompasses theoretical and experimental investigations of the unified description of electromagnetic and weak forces within the Standard Model of particle physics. It focuses on the SU(2)\(_L\) × U(1)\(_Y\) gauge structure, spontaneous symmetry breaking via the Higgs mechanism, and the resulting properties and couplings of W, Z, and photon fields. Research includes precision tests of electroweak observables, renormalization and radiative corrections, flavor and CP-violating processes mediated by weak interactions, global fits to constrain model parameters, and explorations of deviations that may signal physics beyond the Standard Model.
In a talk at the ongoing Rencontres de Moriond conference, the ATLAS collaboration presented the result of its latest test of a key principle of the Standard Model of particle physics known as lepton flavor universality. ...
