CKM Matrix and Standard-Model CP Violation
Jonathan L. Rosner
Abstract
The currently favored model of CP violation is based on phases in the Cabibbo-Kobayashi-Maskawa (CKM) matrix describing the weak charge-changing couplings of quarks. The present status of parameters of this matrix is described. Tests of the theory, with particular emphasis on the study of B meson decays, are then noted. Some remarks are made regarding the possible origin of the baryon asymmetry of the universe; the corresponding coupling pattern of the leptons could shed light on the question. Some possibilities for non-standard physics are discussed.
