Search for a Narrow Resonance Lighter than 200GeV Decaying to a Pair of Muons in Proton-Proton Collisions at sqrt[s]=13TeV. Academic Article uri icon

abstract

  • A search is presented for a narrow resonance decaying to a pair of oppositely charged muons using sqrt[s]=13TeV proton-proton collision data recorded at the LHC. In the 45-75 and 110-200GeV resonance mass ranges, the search is based on conventional triggering and event reconstruction techniques. In the 11.5-45GeV mass range, the search uses data collected with dimuon triggers with low transverse momentum thresholds, recorded at high rate by storing a reduced amount of trigger-level information. The data correspond to integrated luminosities of 137 and 96.6fb^{-1} for conventional and high-rate triggering, respectively. No significant resonant peaks are observed in the probed mass ranges. The search sets the most stringent constraints to date on a dark photon in the 30-75 and 110-200GeV mass ranges.
