The prospects of measuring the properties of the associated VH production via Higgs to diphoton channel are presented. The proposed measurements follow the Run II CMS measurement of the Higgs signal strength consistent with the Standard Model. Based on signal strength measurements, we further study the CP property of the HVV coupling through dedicated machine learning approaches to VH kinematics. A so-called non-local QFT interpretation is also discussed since depending on the energy scale of the non-locality and new physics, it may lead to modifications in the VH production with respect to the SM. These modifications lead to a VH topology with special features, so that our analysis strategy needs to be redesigned. Future plans involving these studies are also presented.
