论文摘要

我们对LHC的散射过程中的树级CP侵入性的标准表达式进行了修改,这在不自轭的初始状态时很重要。基于此,我们提出了一种通用和模型独立的搜索策略,用于探测包含多勒普顿信号中的树级CP-Violation。然后,我们将$ tu \ ell \ ell $和$ tc \ ell \ el \ el $的Tev-Scale 4-Fermion操作员与复杂的Wilson系数一起用作说明性示例,并表明它可以在$ cp nc of lhc访问的$ cp ymmorties $ cp nc $ cap a $} cp rhc cp a {10 \%)(10 \%)$ cp nctries o} fb $^{ - 1} $。

We introduce a modification to the standard expression for tree-level CP-violation in scattering processes at the LHC, which is important when the initial state in not self-conjugate. Based on that, we propose a generic and model-independent search strategy for probing tree-level CP-violation in inclusive multi-lepton signals. We then use TeV-scale 4-fermion operators of the form $tu\ell\ell$ and $tc \ell \ell$ with complex Wilson coefficients as an illustrative example and show that it may generate ${\cal O}(10\%)$ CP asymmetries that should be accessible at the LHC with an integrated luminosity of ${\cal O}(1000)$ fb$^{-1}$.
