SEZIONE DI GENOVA
(E.Santopinto) Seminario di Fenomenologia delle particelle elementari, nella prima metà divulgativo. Evento congiunto con l'Universita' di Genova. Speaker: Prof. Michael Spannowsky (Durham University) Higgsplosion is a dynamical mechanism that introduces an exponential suppression of quantum fluctuations beyond the Higgsplosion energy scale and further guarantees perturbative unitarity in multi-Higgs production processes. I will review the calculations that indicate a factorial growth of the h* -> n h transition amplitude and will outline how such a growth leads to an exponential suppression of large particle virtualities. If realised in nature, Higgsplosion has astonishing consequences for the consistency of the Standard Model. I will discuss these consequences and will present phenomenological implications that could potentially lead to observation of Higgsplosion in future experiments.
