B B ¯ mixing and CP violation in SU ( 2 ) L × SU ( 2 ) R × U ( 1 ) models

B B ¯ mixing and CP violation in SU ( 2 ) L × SU ( 2 ) R × U ( 1 ) models We reexamine the mass mixing and CP violation in the B B ¯ system in general SU ( 2 ) L × SU ( 2 ) R × U ( 1 ) models related to recent measurements without imposing manifest or pseudomanifest left-right symmetry. For certain parameter sets, the right-handed contributions can be sizable in B B ¯ mixing and CP asymmetry in B decays for a heavy W ′ even with a mass about 3 TeV. On the other hand the lower bound on the mass of W ′ can be taken down to approximately 300 GeV. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review D American Physical Society (APS)

Abstract

We reexamine the mass mixing and CP violation in the B B ¯ system in general SU ( 2 ) L × SU ( 2 ) R × U ( 1 ) models related to recent measurements without imposing manifest or pseudomanifest left-right symmetry. For certain parameter sets, the right-handed contributions can be sizable in B B ¯ mixing and CP asymmetry in B decays for a heavy W ′ even with a mass about 3 TeV. On the other hand the lower bound on the mass of W ′ can be taken down to approximately 300 GeV.
