摘要：

We consider the Kaluza-Klein scenario in which gravity propagates in the (4+n)-dimensional bulk of spacetime and the standard model particles an confined to a 3-brane. We calculate the gauge boson self-energy corrections arising from the exchange of virtual gravitons and present our results in the STU formalism. We find that the new physics contributions to S, T and U decouple in the limit that the string scale M-s goes to infinity. The oblique parameters constrain the lower limit on M-s. Taking the quantum gravity cutoff to be M-s, S-parameter constraints impose M-s>1.55 TeV for n = 2 at the 1 sigma level. T-parameter constraints impose M-s > 1.25 (0.75) TeV for n = 3 (6).
