Abstract
A recent suggestion that quantum gravity becomes strong near the weak scale can be probed by the exchange of Kaluza Klein towers of massive gravitons in fermion pair production in annihilation and in Drell-Yan production, including contributions from gluon-gluon fusion, at hadron colliders. These processes are found to provide strong bounds which are essentially independent of the number of extra dimensions. We also demonstrate that angular distributions provide a smoking gun signal for low-scale quantum gravity which cannot be mimicked by other new physics scenarios.
