Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at √s=13 TeV

A search for narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in proton-proton collisions at √ s = 13 TeV with the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 fb−1 . The hypothetical resonance is pr...
