Two Graviton Production at and Hadron Hadron Colliders in the Randall-Sundrum Model
We compute the pair production cross section of two Kaluza Klein modes in the
Randall-Sundrum model at and hadron hadron colliders. These processes
are interesting because they get dominant contribution from the graviton
interaction at next to leading order. Hence they provide a nontrivial test of
the low scale gravity models. All the Feynman rules at next to leading order
are also presented. These rules may be useful for many phenomenological
applications including the computation of higher order loop corrections.Comment: 24 pages, 11 figures, some typos correcte
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
