DESCRIPTION:Speakers: Mr. MARCIANO\, Simone (Università di Roma Tre - INF
 N)\nThe smallness of neutrino masses is one of the most intriguing puzzles
  in the context of particle physics. One of the most natural ways to intro
 duce naturally suppressed masses is the construction of dimension-5 effect
 ive operators\, called Weinberg operators. In the presence of only the sta
 ndard Higgs scalar doublet\, these kinds of operators arise in the three u
 sual seesaw models. In this manuscript\, we want to understand which may b
 e the consequences in this context of the addition of new scalar Higgs mul
 tiplets. We will take into account the possible UV completions of such mod
 els and the phenomenology due to the dimension-6 operators.\n\nhttp://indi
