"We reconsider the impact of heavy vector-like fermions on the couplings of standard model (SM) quarks to the SM gauge bosons W-+/- and Z and to the SM Higgs boson H. Integrating out these fermions at tree level we derive general formulae that can be used in any model containing such particles. We apply these formulae to the case of the lightest Kaluza-Klein (KK) fermions in a Randall-Sundrum (RS) model with a custodial protection of flavour conserving Zd(L)(i)(d) over bar (i)(L) and flavour violating Zd(L)(i)(d) over bar (j)(L) couplings," scientists writing in the Journal of High Energy Physics report.
"We point out that in this model also the couplings of ...
