B 0 s − B0 s Mixing in Leptophobic Z ′ Model

Abstract Leptophobic Z ′ gauge boson appears naturally in many grand unified theories, such as flipped SU(5) or string-inspired E6 models. This elusive particle easily escapes the direct/indirect detections because it does not couple to charged leptons. However, it can generate flavor changing neutral current at tree level. In this letter, we show that the recently measured mass difference, ∆ms...

Theoretical update of B s − B s mixing

We update the theory predictions for the mass difference ∆M s , the width difference ∆Γ s and the CP asymmetry in flavour-specific decays, a s fs , for the B s −B s system. In particular we present a new expression for the element Γ s 12 of the decay matrix, which enters the predictions of ∆Γ s and a s fs. To this end we introduce a new operator basis, which reduces the troublesome sizes of the...
