Lepton Number Violation with Dirac Neutrinos

Presented by Mr. Julian HEECK on 22 Jul 2014 from 16:30 to 16:50
Type: Lepton Flavour Violation and Neutrinos
Track: Lepton Flavour Violation and Neutrinos


We point out that lepton number violation is possible even if neutrinos are of Dirac type, and construct a simple renormalizable model that leads to $\Delta L = 4$. We identify the signature low-energy decay of this new framework as neutrinoless quadruple beta decay and present potential candidate isotopes. In addition, an accompanying leptogenesis mechanism will be discussed that differs qualitatively from standard Dirac leptogenesis.
