The search uses proton-proton collision data at $\\sqrt{s}$ = 13 TeV collected by the CMS experiment at the CERN LHC in 2016$-$2018, corresponding to an integrated luminosity of 13 fb$^{-1}$. Two coupling scenarios are considered, with the resonances coupled either equally to all flavors of quarks or preferentially to bottom quarks. The search targets resonances produced in association with hard initial-state radiation, resulting in a large-radius jet with a two-pronged substructure. The ParticleNet algorithm is used to distinguish resonance decays to bottom quark pairs from lighter quark pairs and to suppress background processes. The invariant jet mass spectrum is scrutinized for peaking excesses over a falling background. No evidence for such resonances is observed. Limits are set on the couplings of new scalar and vector resonances to quarks, representing the most stringent limits to date in the mass range of 50$-$250 GeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.165379.v1/t1","@type":"Dataset","description":"The jet $m_{SD}$ distributions in the low-$p_{b\\bar{b}}$ SR, fitted with the background-only hypothesis.
