Query: Search for low mass vector resonances decaying into quark-antiquark
  pairs in proton-proton collisions at $\sqrt{s} =$ 13 TeV   A search for low mass narrow vector resonances decaying into quark-antiquark
pairs is presented. The analysis is based on data collected in 2017 with the
CMS detector at the LHC in proton-proton collisions at a center-of-mass energy
of 13 TeV, corresponding to an integrated luminosity of 41.1 fb$^{-1}$. The
results of this analysis are combined with those of an earlier analysis based
on data collected at the same collision energy in 2016, corresponding to 35.9
fb$^{-1}$. Signal candidates will be recoiling against initial state radiation
and are identified as energetic, large-radius jets with two pronged
substructure. The invariant jet mass spectrum is probed for a potential narrow
peaking signal over a smoothly falling background. No evidence for such
resonances is observed within the mass range of 50-450 GeV. Upper limits at the
95% confidence level are set on the coupling of narrow resonances to quarks, as
a function of the resonance mass. For masses between 50 and 300 GeV these are
the most sensitive limits to date. This analysis extends the earlier search to
a mass range of 300-450 GeV, which is probed for the first time with jet
substructure techniques.
