  Characteristic features of processes mediated by gauge bosons are discussed
in the framework of theories with large extra dimensions. It is shown that if
gauge bosons propagate in the bulk, then there arises a destructive
interference not only between W and W' (or Z and Z'), but also between W' and
Z' and the Kaluza-Klein towers of higher excitations of W and Z bosons
respectively. Specific calculations are made and plotted for the LHC with the
center of mass energy 14 TeV.
