| Abstract: An inclusive search for a low-mass resonance decaying to two $ \tau $ leptons is presented, probing the mass range from 20 to 60 GeV for the first time at a hadron collider. The search uses proton-proton collision data at $ \sqrt{s}= $ 13.6 TeV corresponding to an integrated luminosity of 61.9 fb$^{-1}$ collected by the CMS experiment in 2022 and 2023. The data is collected using a high-rate trigger stream that records limited event information which allows for lower thresholds. A novel algorithm is used to reconstruct hadronic $ \tau $ decays with very low momentum. No significant excess is observed, and upper limits are set on the production cross section times branching fraction to $ \tau $ lepton pairs. | ||
