ρ parameter constraints on radion phenomenology and a lower bound on Higgs mass
نویسندگان
چکیده
In this paper 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 LEP1 bound on ρ is then used to derive constraints on the radion mass mφ and its vev 〈φ〉. Finally by using the beta function of the higgs self coupling we have determined a lower bound on the higgs mass from the rho parameter constraints on mφ and 〈φ〉. Our results show that for mφ < 600 GeV the rho parameter bound on mh is stronger than the present direct bound from LEPII. E-mail: [email protected] E-mail:[email protected]

Radion Phenomenology in the Randall Sundrum Scenario
Phenomenology of a radion (φ) in the Randall-Sundrum scenario is discussed. The radion couples to the trace of energy momentum tensor of the standard model with a strength suppressed only by a new scale (Λφ) which is an order of the electroweak scale. In particular, the effective coupling of a radion to two gluons is enhanced due to the trace anomaly of QCD. Therefore, its production cross sect...

We investigate the model of warped spatial dimension (popularly known as Randall-Sundrum model) in the light of the muon anomalous magnetic moment, aμ[= (g−2) 2 ]. Using the present theoretical value (based on standard model calculation) and the BNL measurement of muon anomalous magnetic moment, we obtain constraints on radion (required to fix the size of the extra dimension) mass mφ and radion...

متن کاملRadion effects on unitarity in gauge-boson scattering
The scalar field associated with fluctuations in the positions of the two branes, the “radion”, plays an important role determining the cosmology and collider phenomenology of the Randall-Sundrum solution to the hierarchy problem. It is now well known that the radion mass is of order the weak scale, and that its couplings to standard model fields are order O(TeV) to the trace of the energy mome...
