Non-unitary Leptonic Mixing and Leptogenesis
  KTH/Nordita/SU seminar in Theoretical Physics [before December 2013]

Wednesday 17 February 2010
from 11:00 to 12:00
at FA31
Speaker : Mattias Blennow (MPI Munich)
Abstract : Neutrino masses and mixings present one of the few evidence for physics beyond the Standard Model. Many of the models for neutrino mass generation includes the introduction of heavy states with which the neutrinos mix. Upon integrating these states out of the theory, the effective lepton mixing matrix becomes non-unitary. In this seminar, I will discuss the current bounds on such non-unitarity and the possibility of creating a baryon asymmetry in the Early universe through leptogenesis driven by it.
