Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at $\sqrt{s} =$ 13 TeV

Understand

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.
