超对称性与LHC上的黑洞

Supersymmetry versus black holes at the LHC

Arunava Roy, Marco Cavaglia

摘要:

超对称性和额外维度是TeV尺度下新物理学最有希望的两个候选者。在大型强子对撞机上,超对称粒子或超维效应很快就能被观测到。我们提出了一个简单而有效的方法来区分这两种模型:高横动量孤立轻子的分析。用CATFISH黑洞发生器模拟了黑洞事件。超对称模拟使用PYTHIA和ISAJET的组合,后者提供质谱。我们的结果表明,双轻子不变质量的测量提供了一个强有力的签名,以区分超对称性和黑洞事件在大型强子对撞机。对事件形状变量和多轻子事件的分析补充并加强了这一结论。

英文摘要:

Supersymmetry and extra dimensions are the two most promising candidates for new physics at the TeV scale. Supersymmetric particles or extra-dimensional effects could soon be observed at the Large Hadron Collider. We propose a simple but powerful method to discriminate the two models: the analysis of isolated leptons with high transverse momentum. Black hole events are simulated with the CATFISH black hole generator. Supersymmetry simulations use a combination of PYTHIA and ISAJET, the latter providing the mass spectrum. Our results show the measure of the dilepton invariant mass provides a strong signature to differentiate supersymmetry and black hole events at the Large Hadron Collider. Analysis of event-shape variables and multilepton events complement and strengthen this conclusion.
