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 $p p$ collisions at the LHC energies. This would show up as the process $p p \to jet + {E̸}_{T}$ . We calculate the distributions in the jet transverse momentum and rapidity and compare them with the standard model background $p p \to jet + ν \bar{ν}$ . We find that the models with $n \geq 4$ can be probed at the collision energy 14 TeV, while searches at 7 TeV are sensitive to models with $n \geq 6$ only.
