Search for physics beyond the standard model in high-mass diphoton events from proton-proton collisions at s =13 TeV

A search for physics beyond the standard model is performed using a sample of high-mass diphoton events produced in proton-proton collisions at ffiffi s p ¼ 13 TeV. The data sample was collected in 2016 with the CMS detector at the LHC and corresponds to an integrated luminosity of 35.9 fb−1. The...
