B Decays as a Probe of Spontaneous CP-Violation in SUSY Models

TL;DR

This paper investigates how supersymmetric models with spontaneous CP-violation affect B decay asymmetries, revealing significant deviations from Standard Model predictions, applicable to various SUSY frameworks.

Contribution

It demonstrates that spontaneous CP-violation in SUSY models leads to distinct CP-asymmetry predictions in B decays, extending to NMSSM-like and R-parity broken MSSM models.

Findings

CP-asymmetries in B decays differ markedly from SM predictions

Applicable to NMSSM-like models with sterile superfields

Relevant for MSSM with R-parity violation

Abstract

We consider phenomenological implications of susy models with spontaneously broken CP-symmetry. In particular, we analyze CP-asymmetries in B decays and find that the predictions of these models are vastly different from those of the SM. These features are common to NMSSM-like models with an arbitrary number of sterile superfields and the MSSM with broken R-parity.
