A Real CKM Matrix and Physics Beyond the Standard Model
We study the possible existence of a real Cabibbo-Kobayashi-Maskawa (CKM) matrix, with CP violation originating from physics beyond the standard model (SM). We show that present experimental data allow for a real CKM matrix provided that new physics also contributes to ∆mBd by at least 20% of the SM contribution (for ρ > 0), besides generating CP violation in the kaon sector. The naturalness of...
متن کاملCKM Matrix and Standard-Model CP Violation
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...

متن کاملPhysics Beyond the Standard Model
The Standard Model is in good shape, apart possibly from gμ−2 and some niggling doubts about the electroweak data. Something like a Higgs boson is required to provide particle masses, but theorists are actively considering alternatives. The problems of flavour, unification and quantum gravity will require physics beyond the Standard Model, and astrophysics and cosmology also provide reasons to ...
متن کاملPhysics Beyond the Standard Model
I present a brief overview of some exciting possibilities for physics Beyond the Standard Model. I include short discussions of neutrino physics, the strong CP problem and axions, GUTs, large and warped extra dimensions, Little Higgs models and supersymmetry. The chances appear excellent that in the next few years– as the LHC era gets underway– data from a bevy of experiments will point the way...
