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.
