Hadron collider potential for excited bosons search: A Snowmass

M. V. Chizhov, V. A. Bednyakov, J. A. Budagov
The dilepton final states, like e+e- and mu+mu-, are the most clear channels for new heavy neutral resonance search. The main irreducible background is the Drell-Yan process, which usually contributes two orders of magnitude lower than the expected signal under the peak region. In this paper we are focused on the search of the excited bosons Z*, rather than on the well-known Z' bosons from various benchmark models. At present only the ATLAS Collaboration is looking for such excitations at LHC. We compare our evaluations with the official collaboration results at 7TeV, and present our estimations at higher centre-of-mass energies in pp collisions and different luminosities.
