| Abstract: A generic search for a low mass dilepton resonance in Higgs boson decays is conducted in the four-lepton final state. The decay is assumed to proceed via two new particles (beyond the standard model), or one new particle in association with a Z boson. The search uses proton-proton collision data collected by the CMS detector, corresponding to an integrated luminosity of 137 fb$^{-1}$, at a center-of-mass energy $\sqrt{s}= $ 13 TeV. No significant deviation from the standard model expectation is observed. Upper limits at 95% confidence level are set on model-independent cross sections and Higgs boson decay branching fractions. Additionally, limits on dark photon and axion-like particle models are reported. | ||
