The Contributions of Neutral Higgs Bosons to Charmless Nonleptonic B Decays in MSSM

TL;DR

This paper studies how neutral Higgs bosons in the MSSM influence charmless nonleptonic B decays, showing they can significantly affect decay rates and CP violation especially at large tanβ and light Higgs masses.

Contribution

It provides a detailed analysis of neutral Higgs contributions to B decay processes within the MSSM, including operator anomalous dimensions and their impact on decay observables.

Findings

Neutral Higgs penguins can dominate electroweak penguins at large tanβ.

Higgs contributions can significantly alter decay widths.

CP asymmetries are greatly affected by Higgs effects.

Abstract

We investigate the contributions of neutral Higgs bosons to nonleptonic transition $b \to q \bar{s} s, q=d, s$ under the supersymmetric context. Their effects to decay width and CP violation in corresponding exclusive decays are explored. The anomalous dimension matrices of the operators which have to be incorporated to include the contributions of neutral Higgs bosons are given. We find that when tan$\beta$ is large (say, 50) and neutral Higgs bosons are not too heavy (say, 100 GeV), contributions of neutral Higgs penguin can dominate electroweak penguin contributions, and for some processes, they can greatly modify both decay width and CP asymmetry.
