Hadronic B decays in the MSSM with large tan(beta)

TL;DR

This paper investigates non-leptonic B decays within the MSSM framework with large tan(beta), showing current leptonic decay limits restrict observable effects in hadronic decays, with some potential modifications in specific amplitudes but below detection thresholds.

Contribution

It establishes a connection between scalar operator effects in hadronic B decays and leptonic observables, providing new constraints within the MSSM with large tan(beta).

Findings

Leptonic decay limits exclude visible effects in hadronic decays.

Scalar operators can cause order-one modifications in some decay amplitudes.

Such modifications are too small to be detected at current B factories.

Abstract

We present an analysis of non-leptonic B decays in the minimally flavour-violating MSSM with large tan(beta). We relate the Wilson coefficients of the relevant hadronic scalar operators to leptonic observables, showing that the present limits on the Bs->mu+ mu- and B+->tau nu_tau branching fractions exclude any visible effect in hadronic decays. We study the transverse helicity amplitudes of B->VV decays, which exhibit an enhanced sensitivity to the scalar operators, showing that even though an order one modification relative to the SM is not excluded in some of these amplitudes, they are too small to be detected at B factories.
