Search for low mass vector resonances decaying to quark-antiquark pairs in proton-proton collisions at s =13 TeV
A search is reported for a narrow vector resonance decaying to quark-antiquark pairs in proton-proton collisions at ffiffi s p ¼ 13 TeV, collected with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 2.7 fb−1. The vector resonance is produced at large trans...

| Summary: | A search is reported for a narrow vector resonance decaying to quark-antiquark pairs in proton-proton
collisions at ffiffi
s p ¼ 13 TeV, collected with the CMS detector at the LHC. The data sample corresponds to
an integrated luminosity of 2.7 fb−1. The vector resonance is produced at large transverse momenta, with
its decay products merged into a single jet. The resulting signature is a peak over background in the
distribution of the invariant mass of the jet. The results are interpreted in the framework of a leptophobic
vector resonance and no evidence is found for such particles in the mass range of 100–300 GeV. Upper
limits at 95% confidence level on the production cross section are presented in a region of mass-coupling
phase space previously unexplored at the LHC. The region below 140 GeV has not been explored by any
previous experiments. |
