CP Violation in $Wγ$ and $Zγ$ Production

Abstract

We study the capability of a $2 TeV$ $p\overline{p}$ collider with an integrated luminosity of $10 fb^{-1}$ to study CP violation in the processes $p \bar{p} \ra W^\pm γ$ and $p \bar{p} \ra Z γ$. We assume the existence of new CP violating interactions beyond the standard model which we describe with an effective Lagrangian. We find that the study of CP-odd observables would allow this machine to place bounds on CP violating anomalous couplings similar to the bounds that the same machine can place on $\cp$ conserving anomalous couplings. For example it could place the bound $|\tildeκ_γ|<0.1$ at the 95% confidence level.
