Lepton flavor-violating Higgs decays mediated by ultralight gauge boson
Abstract We present an analysis of the lepton-flavor violating decay of the Higgs boson mediated by an ultralight gauge boson, $$\chi $$ χ . Our analysis matches a model generating the lepton flavor-violating interaction $$\bar{\ell }_i\ell _j\chi $$ ℓ ¯ i ℓ j χ at tree level with an effective field...

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