Findings

Potentially detectable CP asymmetries in sbottom decays.

Identification of MSSM parameter space with large CP asymmetries.

Feasibility analysis for observing CP asymmetries at the LHC.

Abstract

We study CP asymmetries in two-body decays of bottom squarks into charginos and tops. These asymmetries probe the SUSY CP phases of the sbottom and the chargino sector in the Minimal Supersymmetric Standard Model. We identify the MSSM parameter space where the CP asymmetries are sizeable, and analyze the feasibility of their observation at the LHC. As a result, potentially detectable CP asymmetries in sbottom decays are found, which motivates further detailed experimental studies for probing the SUSY CP phases.
