Saurabh Bansal, Antonio Delgado, Christopher Kolda, Mariano Quiros

摘要:

我们发现的R-宇称违反(RPV)耦合的最小超对称标准模型,使用Drell-Yan微分截面在大型强子对撞机的限制。具体来说,我们看看在$λ'LQD^c$耦合的约束条件,从单轻子和双轻子数据发表的ATLAS,无论是电子或μ子的最终状态。出18 RPV耦合的LHC至少是潜在的敏感性,通过这种技术,我们发现新的限制12(或13)的平方质量以上1(或2)TeV。我们还表明,可以采用我们的技术,以实现显着更强的界限在高亮度升级的大型强子对撞机。

英文摘要:

We find constraints on R-Parity Violating (RPV) couplings of the minimal supersymmetric standard model, using Drell-Yan differential cross sections at the LHC. Specifically, we look at the constraints on $λ'LQD^c$ couplings from monolepton and dilepton data published by ATLAS, with either electrons or muons in the final state. Out of the 18 RPV couplings to which the LHC is at least potentially sensitive by this technique, we find new limits on 12 (or 13) of them, for squarks masses above 1 (or 2) TeV. We also show that one can employ our techniques to achieve significantly stronger bounds at a high-luminosity upgrade of the LHC.
