| contents | We present an analysis of the lepton-flavor violating decay of the Higgs boson mediated by an ultralight gauge boson, $χ$. Our analysis matches a model generating the lepton flavor-violating interaction $\bar{\ell}_i\ell_jχ$ at tree level with an effective field theory, safeguarding a physical massless $χ$-boson limit of the observables. By utilizing the upper bounds on $H\to\ell_i \bar\ell_j$ decays from CMS and ATLAS Collaborations, we establish an indirect upper limit on the nonstandard decay $H\to\ell_i \bar\ell_jχ$. The analysis encompasses various observables such as the lepton energy spectrum, Dalitz plot distribution, and Lepton Charge and Forward-Backward Asymmetries. |
