B̄→Xsγ in two universal extra dimensions
We calculate the leading order corrections to the B̄→Xsγ decay in the standard model with two large flat universal extra dimensions. We find that the contributions involving the exchange of Kaluza-Klein modes of the physical scalar field a(kl)± depend logarithmically on the ultraviolet cutoff scale...
