摘要:

在大型强子对撞机(LHC)的背景下,研究了一个基准的CP违反超对称的情况下(在文献中称为'CPX-Bio')。它表明,大型强子对撞机,低到中等的累积光度,将能够探测现有的“洞”在$m_{h_1}$ - $\tanβ$平面,这不能排除由大型电子正电子对撞机的数据。这可以通过与顶夸克和顶夸克对相关的希格斯玻色子的产生来实现,从而产生信号\emph{dilepton + $\leq{5}$ jets (including 3 b-jets) + missing ${p_T}$}。在LHC中,用中等数量的数据也可以有效地区分这种违反CP的超对称场景与其他竞争场景。

英文摘要:

A benchmark CP-violating supersymmetric scenario (known in the literature as `CPX-scenario') is studied in the context of the Large Hadron Collider (LHC). It is shown that the LHC, with low to moderate accumulated luminosity, will be able to probe the existing `hole' in the $m_{h_1}$-$\tanβ$ plane, which cannot be ruled out by the Large Electron Positron Collider data. This can be done through associated production of Higgs bosons with top quark and top squark pairs leading to the signal \emph{dilepton + $\leq{5}$ jets (including 3 b-jets) + missing ${p_T}$}. Efficient discrimination of such a CP-violating supersymmetric scenario from other contending ones is also possible at the LHC with a moderate volume of data.
