Leptonic flavor structure in the brane shifted extra dimensional seesaw mechanism
Abstract We discuss the leptonic flavor structure generated by a brane shifted extra dimensional seesaw model with a single right handed neutrino in the bulk. In contrast to previous works, no unitarity approximation for the $$3 \times 3$$ 3×3 submatrix has been employed. This allows to study phenom...

description | Abstract We discuss the leptonic flavor structure generated by a brane shifted extra dimensional seesaw model with a single right handed neutrino in the bulk. In contrast to previous works, no unitarity approximation for the $$3 \times 3$$ 3×3 submatrix has been employed. This allows to study phenomenological signatures such as lepton flavor violating decays. A strong prediction of the model, assuming CP conservation, are the ratios of flavor violating charged lepton decay and Z decay branching ratios which are correlated with the neutrino mixing angles and the neutrino mass hierarchy. Furthermore, it is possible to obtain branching ratios for $$\mu \rightarrow e \gamma $$ μ→eγ close to the experimental bounds even with Yukawa couplings of order one. |
