LHC超对称级联衰变中的顶夸克增强

Boosted top quarks in supersymmetric cascade decays at the LHC

Priyotosh Bandyopadhyay, Biplob Bhattacherjee

摘要:

在大型强子对撞机中,一般的超对称级联可以成为顶夸克的来源。具体来说,第三代夸克和胶子是顶夸克的主要来源,也可以被提升。在这篇文章中,我们已经表明,喷流子结构算法可以非常有用的在识别这样的升压顶夸克的级联。我们取包含三个喷注加零轻子加丢失能量的末态,尝试用在LHC上有很好应用前景的top tag技术重建至少一个强子衰变的顶夸克。

英文摘要:

At the LHC, a generic supersymmetric cascade can be a source of top quark. Specifically third generation squarks and gluino are the major sources of top quark which could also be boosted. In this article, we have shown that jet substructure algorithm can be very useful in identifying such boosted top quarks in the cascade. We take inclusive three jets plus zero lepton plus missing energy final state and try to reconstruct at least one hadronically decaying top quark by using top tagging techniques which has good prospect at the LHC.
