B511 (2001) 251-256 | Subject: | hep-ph | Affiliation: | Yonsei Univ.) and Jeonghyeon Song (KIAS | Abstract: | We study the effects of the Kaluza-Klein gravitons in the Randall-Sundrum model on the recent BNL measurements of the muon (g-2) deviation from the standard model prediction. By examining the J-partial wave unitarity bounds of the elastic process gamma+gamma->gamma+gamma, the cut-off on the number of massive KK gravitons, n_c, has been introduced. We found that the recently measured (Delta a_mu) can be accommodated in the RS model, within the natural parameter space allowed by the perturbative unitarity. For example, dozens (hundreds) of the n_c for Lambda_pi=1-2 TeV (3 TeV) can explain the reported Delta a_mu. | Source: | arXiv, hep-ph/0103127 | Services: | Forum | Review | PDF | Favorites |
