terrà un seminario dal titolo:
“Massless Dark Photons at Colliders”
Abstract:
“Recent models, possibly explaining the fermion-mass hierarchy, predict the existence of a massless dark
photon. Its interactions are restricted to a hidden sector made up of massive dark fermions (which are
promising dark-matter candidates), and heavier scalar messengers connecting the SM with the dark
fields. Thanks to the nondecoupling properties of the Higgs boson, exotic Higgs interactions with the
invisible dark photon can show up at present and future colliders with measurable rates. Predictions for
new Higgs signatures and corresponding rates are presented. A new class of FCNC’s mediating SM
fermion decays into massless dark photons are also discussed.”
Tutti gli interessati sono invitati a partecipare.
