We analyze the theoretical prediction on the branching ratio of B→Xsγ to order ΛEW2/ΛKK2 in extension of the standard model with a warped extra dimension and the custodial symmetry SU(3)c×SU(2)L×SU(2)R×U(1)X×PLR, where ΛKK denotes the energy scale of low-lying Kaluze-Klein excitations and ΛEW denotes the electroweak energy scale. Contributions from the in nite series of Kaluze-Klein excitations are summed over through the residue theorem. The numerical result indicates that the present experimental data constrain the parameter space of the concerned model strongly. 相似文献
