Search for dijet resonances in proton–proton collisions at s=13TeV and constraints on dark matter and other models

Search for dijet resonances in proton–proton collisions at s=13TeV and constraints on dark matter and other models

A search is presented for narrow resonances decaying to dijet final states in proton–proton collisions at √s = 13 TeV using data corresponding to an integrated luminosity of 12.9 fb−1. The dijet mass spectrum is well described by a smooth parameterization and no significant evidence for the produc...
