(Pseudo-) Scalar Operators in the MSSM and B to phi K^*, K eta(') Decays

TL;DR

This paper investigates how scalar and pseudoscalar operators from the MSSM influence B meson decays, revealing that accounting for weak annihilations is crucial to resolving polarization puzzles without requiring new physics effects.

Contribution

It demonstrates that the polarization puzzle in B to phi K^* decays can be explained within the MSSM framework when weak annihilations are included, reducing the need for new physics explanations.

Findings

Weak annihilations are essential to resolve the polarization puzzle.

Scalar/pseudoscalar operators have limited impact when annihilations are considered.

New physics effects are suppressed in the polarization amplitudes.

Abstract

We study the effect of b to s sbar s scalar/pseudoscalar operators, originating from penguin diagrams of neutral Higgs bosons in the MSSM, in B to K eta(') and B to phi K^* decays. These operators can be Fierz-transformed into tensor operators, and the resultant tensor operators could affect the transverse polarization amplitudes in B to phi K^* decays. We find that only when the weak annihilations in B to phi K^* into account, the polarization puzzle can be resolved, so that new physics effects are strongly suppressed and no more relevant to the enhancement of the transverse modes in B to phi K^* decays.
