Özet

A search is presented for excited quarks of light and heavy flavor that decay to ?+jetfinal states. The analysis is based on data corresponding to an integrated luminosity of 35.9fb?1collected by the CMS experiment in proton–proton collisions at ?s=13 TeVat the LHC. A signal would appear as a resonant contribution to the invariant mass spectrum of the ?+jetsystem, above the background expected from standard model processes. No resonant excess is found, and upper limits are set on the product of the excited quark cross section and its branching fraction as a function of its mass. These are the most stringent limits to date in the ?+jetfinal state, and exclude excited light quarks with masses below 5.5TeVand excited b quarks with masses below 1.8TeV, assuming standard model like coupling strengths
