ETmiss performance in events with Gamma, Z and dijets using 0.8 fb-1 of 2016 Data

In this note we summarize the Missing Energy (ETmiss) performances with the first 0.8 fb-1 proton-proton collisions at 13 TeV recorded by CMS in 2016. Response and resolution of ETmiss are measured in events with an identified Z boson and an isolated photon. Events with anomalous ETmiss are studied and the performance of the algorithm used to identify and remove these events is presented.
