General lepton mixing in holographic composite Higgs models

We introduce a scenario of lepton mixing in holographic composite Higgs models based on non-abelian discrete symmetries of the form G(f) = X x Z(N), broken to Z(2) x Z(2) x Z(N) in the elementary sector and to Z(N)((D)) in the composite sector with Z(N)((D)) being the diagonal subgroup of a Z(N) subset of X and the external Z(N). By choosing X = Delta(96) or Delta(384), a non-vanishing theta(13) of order 0.1 is naturally obtained. We apply our considerations to a 5D model in warped space for the particular cases of X = S-4, A(5), Delta(96) and Delta(384) and N = 3 or 5. Lepton flavour violating processes and electric dipole moments are well below the current bounds, with the exception of mu -> e gamma that puts a very mild constraint on the parameter space of the model, for all presented choices of G(f).
