Description
Separation of electroweak from strong $Z\gamma$ production is a very challenging task due to identical final states of such processes. The only difference is the origin of two leading jets. Rectangular cuts on jet kinematical variables from ATLAS Run1 $Z\gamma$ analysis were improved using machine learning techniques. New selection variables were also tested. The reached expected significance of separation for ATLAS Run2 conditions and 36 $fb^{-1}$ amount of data is $6\sigma$.
