Single Photon Signals for Warped Quantum Gravity at a Linear e+-e- Collider

We study the `single photon’ process e± e- -> gamma nu nubar with contributions due to exchange of massive gravitons in the Randall- Sundrum model of low-scale quantum gravity. It is shown that for significant regions in the parameter space, this process unambiguously highlights the resonance structure of the graviton sector. Even in the non-resonant part of the parameter space, we show that comparison with the benchmark process e± e- -> mu± mu- can clearly distinguish signals for warped gravity from similar signals for large extra dimensions.
