DESCRIPTION:Leptogenesis is an attractive theory to explain the origin of 
 the matter-antimatter asymmetry of the universe because it's based on a si
 mple extension of the Standard Model which also allows to understand why t
 he neutrinomasses are so tiny. In leptogenesis scenarios a lepton asymmetr
 y is produced in the out of equilibrium decay of heavy Majorana neutrinos 
 in the early universe\, which is then partially converted into a baryon as
 ymmetry by the action of non perturbative processes of the Standard Model.
  In this talk we will describe the impact for leptogenesis of new U(1) gau
 ge bosons coupled to the heavy Majorana neutrinos. We will show how the al
 lowed region of the parameter space is modified in the presence of Z' boso
 ns and we will comment on the minimum reheating temperature that is requir
 ed for these models to be successful.\n\nhttps://indico.ific.uv.es/event/1
