Lepton Masses and Flavor Violation in Randall Sundrum Model

Understand

Lepton masses and mixing angles via localization of 5D fields in the bulk are revisited in the context of Randall-Sundrum models.

• The Higgs is assumed to be localized on the IR brane.
• Three cases for neutrino masses are considered: (a) The higher dimensional LH.LH operator (b) Dirac masses (c) Type I see-saw with bulk Majorana mass terms.
• Neutrino masses and mixing as well as charged lepton masses are fit in the first two cases using $\chi^2$ minimisation for the bulk mass parameters, while varying the $\mathcal{O}(1)$ Yukawa couplings between 0.1 and 4.
