Beautiful CP Violation
CP violation is observed to date only inK decays and is parameterizable by a single quantity ǫ. Because it is one of the least understood phenomena in the Standard Model and holds a clue to baryogenesis, it must be investigated further. Highly specialized searches in K decays are possible. Effects in B decays are much larger. In addition to the traditional Bd → J/ψKS , ππ asymmetries, CP violat...
متن کاملCP-Violation with Bosons
We formulate the conditions under which a purely bosonic theory (without fermions) containing neutral spin-0 particles and vector (gauge) bosons violates the CP-symmetry through the presence of CP-even and CP-odd operators in the Lagrangian. This is done without reference to explicitly CP-violating scalar sector of extended standard models (SM) with two or more Higgs doublets. The Lagrangian ex...
متن کاملCp Violation
Three possibilities for the origin of CP violation are discussed: (1) the Standard Model in which all CP violation is due to one parameter in the CKM matrix, (2) the superweak model in which all CP violation is due to new physics and (3) the Standard Model plus new physics. A major goal of B physics is to distinguish these possibilities. CP violation implies time reversal violation (TRV) but di...
متن کاملCp Violation*
Predictions for CP violation in the three generation Standard Model are reviewed based on what is known about the Cabibbo-Kobayashi-Maskawa matrix. Application to the I(and B meson systems are emphasized.
متن کاملBosons with Explicit CP Violation
We study Higgs boson decays in the minimal supersymmetric standard model where the tree–level CP invariance of the Higgs potential is explicitly broken by loop effects of soft CP–violating Yukawa interactions related to scalar quarks of the third generation. The scalar–pseudoscalar mixing among two neutral CP–even Higgs bosons and one CP–odd Higgs boson due to explicit CP violation modifies the...
