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.Comment: Published version; figures change
