DESCRIPTION:Speakers: Mr. ANGEL EDUARDO\, Zecua Hernández (BUAP)\nThis wo
 rk investigates Higgs boson decays into invisible particles within extensi
 ons of the Standard Model featuring a new (U_D(1)) gauge symmetry associat
 ed with a massless dark photon. Two theoretical frameworks are considered:
  one involving fermionic mediators and another involving scalar mediators.
  Using one-loop amplitude calculations\, several decay channels are studie
 d\, and their viability is assessed through experimental constraints and p
 erturbativity requirements. The results show that the scalar mediator mode
 l can yield a larger branching ratio for (h\\to AA') than the fermionic mo
 del\, highlighting the potential of these processes as probes of new physi
 cs beyond the Standard Model.\n\nhttps://indico.nucleares.unam.mx/event/26
