味破坏夸克和胶子衰变

Flavour violating squark and gluino decays

Tobias Hurth, Werner Porod

摘要:

我们考虑的情况下,大味违反条目的squark质量矩阵,专注于第二代和第三代squarks之间的混合。这些条目支配着两者,一方面是违反低能观测的味,另一方面是夸克和胶子衰变。我们首先讨论了由于B工厂和Tevatron的最新数据对参数空间的限制。然后,我们考虑味道违反夸克和胶子衰变,并表明,他们仍然可以典型的顺序10%,尽管从低能量数据的严格限制。最后,我们简要地评论搜索和参数确定在未来的对撞机实验,如即将到来的大型强子对撞机或未来的国际直线对撞机的影响。

英文摘要:

We consider scenarios with large flavour violating entries in the squark mass matrices focusing on the mixing between second and third generation squarks. These entries govern both, flavour violating low energy observables on the one hand and squark and gluino decays on the other hand. We first discuss the constraints on the parameter space due to the recent data on B mesons from the B factories and Tevatron. We then consider flavour violating squark and gluino decays and show that they can still be typically of order 10% despite the stringent constraints from low energy data. Finally we briefly comment on the impact for searches and parameter determinations at future collider experiments such as the upcoming LHC or a future International Linear Collider.
