Search for low-mass dilepton resonances in Higgs boson decays to four-lepton final states in proton–proton collisions at vs=13TeV

Abstract: A search for low-mass dilepton resonances in Higgs boson decays is conducted in the four-lepton final state. The decay is assumed to proceed via a pair of beyond the standard model particles, or one such particle and a Z boson. The search uses proton?proton collision data collected with the CMS detector at the CERN LHC, corresponding to an integrated luminosity of 137fb?1, at a center-of-mass energy s?=13TeV. No significant deviation from the standard model expectation is observed. Upper limits at 95% confidence level are set on model-independent Higgs boson decay branching fractions. Additionally, limits on dark photon and axion-like particle production, based on two specific models, are reported.
