In this Letter we determine the contribution of a light stabilized radion to the weak isospin violating ρ parameter by using an ultraviolet momentum cut off as the regulator. The LEPI bound on ρ new is then used to derive constraints on the radion mass m φ and its vev <φ>. Finally by using the beta function of the Higgs self coupling we have determined a lower bound...
In this Letter we determine how the beta function of the Higgs self coupling λ at one loop order is modified by a light stabilized radion in the Randall–Sundrum model. We then use the modified beta function to derive a lower bound on the radion vev 〈φ〉, both for perturbative and non-perturbative values of λ at the ultra violet cut off Λ. The lower bound on 〈φ〉 is obtained by demanding that the renormalized...
