Cp Violation and Quark Mixing Cp Violation and Quark Mixing
Measurements of CP asymmetries in B decays will soon be made at B factories and hadron machines. In light of this, we review and update the profile of the CKM unitarity triangle and the resulting CP asymmetries in B decays. This is done both in the standard model and in several variants of the minimal supersymmetric standard model (MSSM), which are characterized by a single phase in the quark f...
متن کاملFermion masses, neutrino mixing and CP violation from the anti-grand unification model
The fermion masses and mixing angles are fitted using only 3 free parameters in a non-supersymmetric extension of the Standard Model, with new approximately conserved chiral gauge quantum numbers broken by a set of Higgs fields. The fundamental mass scale of this anti-grand unification model is given by the Planck mass. We also calculate neutrino mixing angles and masses, as well as CP violatio...
متن کاملFinite Grand Unified Theories and The Quark Mixing Matrix
In super Yang–Mills theories, under certain conditions satisfied by the spectrum and the Yukawa couplings, the beta functions will vanish to all orders in perturbation theory. We address the generation of realistic quark mixing angles and masses in such finite Grand Unified Theories. Working in the context of finite SUSY SU(5), we present several examples with realistic quark mixing matrices. N...
متن کاملQuark Mixing and CP Violation
We review the historical developments leading to the CabibboKobayashi-Maskawa (CKM) quark mixing matrix. Present status of the CKM matrix from direct measurements is summarized, giving also the present profile of the unitarity triangle. CP Violation in the K0 K0 complex and in B-meson decays are discussed in the context of
متن کاملQuark Mixing and Cp Violation
The present status of quark mixing and CP violation in the s tandard six quark model is reviewed in view of the recent experimental ( b ---* u transit ion, B 0 / ~ 0 mixing, el/e) and theoretical (progress in the calculation of the hadronic matr ix elements) developments. Implications of the da ta on B 0 / ~ 0 mixing, ~ and el/e for the value of the top quark mass (mr) are discussed in detail. ...
