在LHC上双光子独占产生超对称对

Two-photon exclusive production of supersymmetric pairs at the LHC

K. Piotrzkowski, N. Schul

摘要:

在LHC上双光子独家产生的带电超对称对有一个干净而独特的签名-两个非常向前散射的质子和两个相反的带电轻子集中产生。对于低质量的超对称性情景,预计会有显著的横截面,背景过程得到很好的控制。前向质子能量的测量将允许右手slepton和LSP的质量重建与几个GeV的分辨率。本文讨论了在中心和前向探测器中事件之间的偶然巧合所导致的高亮度下减少背景的方法。

英文摘要:

The two-photon exclusive production of charged supersymmetric pairs at the LHC has a clean and unique signature - two very forward scattered protons and two opposite charged leptons produced centraly. For low-mass SUSY scenarios, significant cross-sections are expected and background processes are well controlled. Measurement of the forward proton energies would allow for mass reconstruction of right-handed sleptons and the LSP with a few GeV resolution. Methods to reduce backgrounds at high luminosity resulting from accidental coincidences between events in the central and forward detectors are discussed.
