Search for heavy resonances decaying to b quarks in proton-proton collisions at $\sqrt{s}=$ 13 TeV
Abstract: Searches are performed for resonances decaying to two jets, with at least one jet originating from a b quark, in proton-proton collisions at $\sqrt{s}=$ 13 TeV. The dataset corresponds to an integrated luminosity of 137 fb$^{-1}$ collected by the CMS detector at the LHC. Jets are identified as containing energetic b hadrons using a deep neural network b tagger. The invariant mass spectrum of b-tagged dijets is well described by a smooth parameterization and no evidence for the production of new particles is observed. Cross-section upper limits are set on resonances decaying into b quarks. These limits exclude at 95% confidence level models of Z' bosons with a mass less than 2.4 TeV, and an excited b quark with mass less than 4.0 TeV.
