Higgs Phenomenology in Warped Extra-Dimensions with a 4th Generation

Understand

We study a warped extra-dimension scenario where the Standard Model fields lie in the bulk, with the addition of a fourth family of fermions.

• We concentrate on the flavor structure of the Higgs couplings with fermions in the flavor anarchy ansatz.
• Even without a fourth family, these couplings will be generically misaligned with respect to the SM fermion mass matrices.
• The presence of the fourth family typically enhances the misalignment effects and we show that one should expect them to be highly non-symmetrical in the ${(34)}$ inter-generational mixing.
