Vector bosons escaping from the brane: $e^{+}{e}^{-}\to \gamma +$ nothing

Abstract

We consider phenomenological consequences of RS2-n model with infinite extra dimension, namely, the production, in high energy collisions, of a photon or Z-boson escaping from our brane in association with a photon remaining on the brane. This would show up as process $e^{+}{e}^{-}\to \gamma +$nothing. We compare the signal with the Standard Model background coming from $e^{+}{e}^{-}\to \gamma \bar{\nu }\nu$. We also make a comparison with $e^{+}{e}^{-}\to \gamma +$nothing in the ADD model.
