Discovering baryon-number violating neutralino decays at the LHC

Jonathan M. Butterworth, John R. Ellis, Are R. Raklev, Gavin P. Salam

摘要:

最近,人们对利用单喷流质量和喷流子结构来识别LHC中强子衰变的助推粒子产生了很大的兴趣。我们发展这些想法,以解决具有挑战性的情况下,一个中性伴子衰变到三个夸克模型重子违反R-宇称。这些衰变以前被发现淹没在QCD背景。我们证明了第一次,这样的衰变可能会直接观察到在大型强子对撞机具有很高的意义,通过利用其复合射流分解成subjets的尺度特性。

英文摘要:

Recently there has been much interest in the use of single-jet mass and jet substructure to identify boosted particles decaying hadronically at the LHC. We develop these ideas to address the challenging case of a neutralino decaying to three quarks in models with baryonic violation of R-parity. These decays have previously been found to be swamped by QCD backgrounds. We demonstrate for the first time that such a decay might be observed directly at the LHC with high significance, by exploiting characteristics of the scales at which its composite jet breaks up into subjets.
