Yetkin, Elif Aslı2020-12-082020-12-082017-09-15https://hdl.handle.net/11411/2790https://doi.org/10.1103/PhysRevLett.119.111802A search is reported for a narrow vector resonance decaying to quark-antiquark pairs in proton-proton collisions at root s = 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.eninfo:eu-repo/semantics/openAccessArticle2-s2.0-8503015649410.1103/PhysRevLett.119.11180228949210Q1Q1WOS:000410897100001
