Testable (g−2)μ contribution due to a light stabilized radion in the Randall–Sundrum model Original Research Article

In this paper we calculate the (g−2)μ contribution due to a light stabilized radion using the radion couplings both to the kinetic energy and the mass of the muon. We find that the radion mediated muon anomaly (ar) is a calculable quantity free from powerlike ultraviolet divergences. We have estimated ar both for Λ⪢mφ⪢mμ and Λ⪢mφ≈mμ. Our results show that under the first (second) condition the radion mediated muon anomaly can be detected with the ultimate future precision for measuring the muon anomaly provided 〈φ〉 is less than 425 (600) GeV. Whereas with the present precision ar can be detected provided 〈φ〉 is less than 250 GeV in the first case and 375 GeV in the second case.
