Probe CP violation in $H\to \gamma Z$ through forward-backward asymmetry

Xuan Chen, Gang Li, Xia Wan

We suggest that the forward-backward asymmetry $(A_{FB})$ of the charged leptons in $gg\to H\to \gamma Z\to \gamma {\ell }^{-}{\ell }^{+}$ process could be used to probe the CP violating $H\gamma Z$ coupling wh…
