Left-handed Currents and Cp Violation
An analysis is presented of a model for CP violation duc to Kobayashi and IVaskawa, which has six quarks and purely left-handed currents. The model can reproduce approximately results of the Glashow, lliopotilos and Maiani four-quark model in CP con..erving processes. It gives a close approximation to superweak predictions for 6"1' violation in common K decays, whatever the masses of the fifth ...
متن کاملRight - handed currents , CP violation , and B →
Precision CP violation measurements in rare hadronicB decays could provide clean signatures of parity symmetric new physics, implying the existence of SU(2)L × SU(2)R×U(1)B−L×P symmetry at high energies. New contributions to the weak scale Hamiltonian which respect parity to O(1%) in supersymmetric realizations are compatible with an SU(2)R breaking scale MR ≤ MGUT, implying that sensitivity to...
متن کاملη′KS at B-factories Suggest New CP Violation in Left-Handed Squark Mixing
Recent results on the mixing-induced CP asymmetries of B → φK0 and B → η′KS measured at B-factories appear to indicate discrepancies from the Standard Model expectation. Explanation of this possible anomaly is given in the context of supersymmetric extension of the Standard Model. It is shown that the present data, if the average of two experiments is taken, implies additional CP violation appe...
متن کاملEnhanced contribution to quark and neutron electric dipole moments with small mixing of right-handed currents and CKM CP violation
We study the light quark and the neutron electric dipole moments (EDMs) under the assumptions that the CP source is still in the usual CKM matrix and that there is a small mixing of right-handed charged currents in the quark sector. We find that the EDMs arise already at two loop order that are much larger than the standard model (SM) result even for a small mixing.
متن کاملCp 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...
