| Abstract: A general search is presented for a low-mass $\tau^-\tau^+$ resonance produced in association with a bottom quark. The search is based on proton-proton collision data at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. The observed data are consistent with the standard model expectation. Upper limits are determined for two hypothetical signal models: a light pseudoscalar Higgs boson decaying to a pair of $\tau$ leptons produced in association with bottom quarks, and a low-mass boson X decaying in a $\tau$ lepton pair that is produced in the decay of a bottom-like quark B such that $\mathrm{B}\to \mathrm{bX}$. Masses between 25 and 70 GeV are probed for the light pseudoscalar boson, and 20 to 70 GeV for the X boson. Through event selections that are optimized for vector-like quarks, the search results extend the reach for new particles to a previously unexplored phase space. | ||
