LHC signatures of vector boson emission from brane to bulk

Abstract

In the framework of the RSII-n model with n compact and one infinite extra dimensions, we study the production of Z-bosons and photons, which escape into the bulk, in association with a jet in pp collisions at the LHC energies. This would show up as the process pp -> jet+bulk. We calculate the distributions in the jet transverse momentum and rapidity and compare them with the Standard Model background pp->jet +ν\barν.We find that the models with n>3 can be probed at the collision energy 14 TeV, while searches at 7 TeV are sensitive to models with n>5 only.
