B -> rho K and B -> pi K^* decays in SCET

TL;DR

This paper investigates how supersymmetric gluino contributions within Soft Collinear Effective Theory can enhance CP asymmetries in B meson decays, potentially explaining experimental anomalies in B -> pi K^* and B -> rho K modes.

Contribution

It introduces a detailed analysis of non-minimal flavor SUSY effects on B decay CP asymmetries using the Mass Insertion Approximation within SCET, highlighting potential new physics explanations.

Findings

Gluino contributions can significantly increase CP asymmetries.

The analysis aligns theoretical predictions with experimental data.

Supersymmetry effects could resolve the B -> K pi puzzle.

Abstract

Exploring hints of New Physics in the decay modes B -> pi K^* and B -> rho K can shed light on the B -> K pi puzzle. In this talk we discuss supersymmetric contributions to the direct CP asymmetries of the decays B -> pi K^* and B -> rho K within Soft Collinear Effective Theory. We consider non-minimal flavor SUSY contributions mediated by gluino exchange and apply the Mass Insertion Approximation in the analysis. We show that gluino contributions can enhance the CP asymmetries and accommodate the experimental results.
