$B_s-\bar{B}_s$ mixing and $B_s \to KK$ decays within supersymmetry

TL;DR

This paper explores how supersymmetry can cause significant deviations from the Standard Model in CP asymmetries of B_s to KK decays, despite constraints from B_s mixing measurements.

Contribution

It demonstrates that large flavor mixing in the MSSM can lead to observable effects in B_s decay CP asymmetries, highlighting a promising channel for supersymmetry detection.

Findings

Large deviations in CP asymmetries are possible within MSSM.

Constraints from B_s mixing do not eliminate the potential for new physics signals.

B_s to KK decays are promising for supersymmetry searches.

Abstract

We consider the constraint of $B_s-\bar{B}_s$ mass difference, $\Delta m_s$, on an MSSM scenario with large flavor mixing. Even with this constraint, we show that a large deviation from the SM in CP asymmetries of $B_s \to KK$ decays is still possible, making this channel promising in search for supersymmetry.
