We study the `single photon' process e+- e- -> gamma nu nubar withcontributions due to exchange of massive gravitons in the Randall- Sundrummodel of low-scale quantum gravity. It is shown that for significant regions inthe parameter space, this process unambiguously highlights the resonancestructure of the graviton sector. Even in the non-resonant part of theparameter space, we show that comparison with the benchmark process e+- e- ->mu+- mu- can clearly distinguish signals for warped gravity from similarsignals for large extra dimensions.Comment: Published version; figures change
