Description

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. Then, as an illustrative example, we show that higher-dimension TeV-scale 4-fermion operators of the form tuℓℓ and tcℓℓ with complex Wilson coefficients can generate CP asymmetries of O(10%), that should be accessible at the LHC with an integrated luminosity of O(1000) fb$^{−1}$.
