Searches for W′ and Z′ in models with large extra dimensions

摘要

We discuss the characteristic features of processes mediated by intermediate gauge bosons in the framework of theories with large extra dimensions and show that if gauge bosons propagate in the entire multidimensional space, then a destructive interference arises not only between W and W′ (or Z and Z′) but also between W′ and Z′ and the respective Kaluza-Klein towers of higher excitations of W and Z bosons. We perform and graphically present calculations for the LHC with the center-of-mass energy 14 TeV.
