英文摘要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 root s = 13 tev with the cms detector at the lhc, corresponding to an integrated luminosity of 35.9 fb(-1). the hypothetical resonance is produced with sufficiently high transverse momentum that its decay products are merged into a single jet with two-prong substructure. a signal would be identified as a peak over a smoothly falling background in the distribution of the invariant mass of the jet, using novel jet substructure techniques. no evidence for such a resonance is observed within the mass range of 50-300 gev. upper limits at 95% confidence level are set on the production cross section, and presented in a mass-coupling parameter space. the limits further constrain simplified models of dark matter production involving a mediator interacting between quarks and dark matter particles through a vector or axial-vector current. in the framework of these models, the results are the most sensitive to date, extending for the first time the search region to masses below 100 gev.
