摘要：

Deviations from standard electroweak physics arise in the framework of a Randall-Sundrum model, with matter and gauge fields in the bulk and the Higgs field localized on the TeV brane. We focus in particular on modifications associated with the weak mixing angle. Comparison with the electroweak precision data yields a rather stringent lower bound of about 10 TeV on the masses of the lowest Kaluza-Klein excitation of the W- and Z-bosons. With some optimistic assumptions the bound could be lowered to about 7 TeV. (C) 2002 Elsevier Science B.V. All rights reserved.
