MSSM中的味违反及其对碰撞器上top和squark搜索的影响

Flavor violation in the MSSM and implications for top and squark searches at colliders

Andreas Crivellin

摘要:

在这篇文章中,我回顾了味道物理学和对撞机物理学之间的一些联系。第一部分讨论了右手带电电流对确定CKM元素V_ub的影响。结果表明,这种有效的右手W-耦合可以产生在MSSM,这将导致在大型强子对撞机的单顶生产相当大的增强。本文的第二部分着重讨论了由K介子和D混合引起的左手方子质量分裂的限制。这种质量分裂对对撞机上的夸克衰变链有着有趣的影响。

英文摘要:

In this article I review some connections between flavor physics and collider physics. The first part discusses the effect of right-handed charged currents on the determination of the CKM elements V_ub. It is shown that such an effective right-handed W-coupling can be generated in the MSSM which would lead to a sizable enhancement of single-top production at the LHC. The second part of this article focuses on the constraints on the mass splitting between left-handed squarks from Kaon and D mixing. Such a mass splitting has interesting consequences for squark decay chains at colliders.
