用ATLAS探测器寻找缺少横能和至少三个b喷注的末态胶子对产生的顶和底方子

Search for top and bottom squarks from gluino pair production in final states with missing transverse energy and at least three b-jets with the ATLAS detector

ATLAS Collaboration

摘要:

这封信报告了在LHC上使用ATLAS探测器在sqrt(s)= 7 TeV的4.7 fb^-1 pp碰撞中寻找由胶子对产生的顶方子和底方子的结果。搜索是在大失踪的横向动量和至少三个喷流确定为源自一个b夸克的事件。排除限制提出了各种各样的Gluino介导的模型与Gluino群众高达1 TeV排除。

英文摘要:

This letter reports the results of a search for top and bottom squarks from gluino pair production in 4.7 fb^-1 of pp collisions at sqrt(s) = 7 TeV using the ATLAS detector at the LHC. The search is performed in events with large missing transverse momentum and at least three jets identified as originating from a b-quark. Exclusion limits are presented for a variety of gluino-mediated models with gluino masses up to 1 TeV excluded.
