We discuss how to construct genuine CP-odd observables at the LHC. We classify the
observables according to the even and odd properties under the naive T-transformation (Tˆ).
There are two classes of observables of our interests: CP-odd and Tˆ-even; CP-odd and Tˆ-
odd. We expect them to have broad applications to many processes in theories beyond
Standard Model with CP violation. For the purpose of illustration, we use simple example of
W+ W− production and subsequent decays at the LHC, where the CP violation effects are …
We discuss how to construct genuine CP-odd observables at the LHC. We classify the observables according to the even and odd properties under the naive T-transformation (Tˆ). There are two classes of observables of our interests: CP-odd and Tˆ-even; CP-odd and Tˆ-odd. We expect them to have broad applications to many processes in theories beyond Standard Model with CP violation. For the purpose of illustration, we use simple example of W+W production and subsequent decays at the LHC, where the CP violation effects are parameterized by effective CP-violating operators of WWZ coupling. We find significant sensitivity to the CP-odd couplings.
