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.
Dark matter particles could be mediators of the interaction between electrons and atomic nuclei, as shown by a study conducted by junior group leader, Dr. Konstantin Gaul, Dr. Lei Cong, and Professor Dr. Dmitry Budker, of ...
