sbottom衰变中的CP破坏

CP violation in sbottom decays

Frank F. Deppisch, Olaf Kittel

摘要:

我们研究CP不对称的两体衰变的底部方成charginos和顶部。这些不对称性探测了最小超对称标准模型中sbottom和chargino扇区的超对称CP相。我们确定的MSSM参数空间的CP不对称性是相当大的,并分析其观察在LHC的可行性。其结果是,潜在的可检测的CP不对称性在sbottom衰变中被发现,这激发进一步详细的实验研究,探测超对称CP相位。

英文摘要:

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.
