Phys. Rev. Lett. 82, 4765–4768 (1999)Indirect Collider Signals for Extra DimensionsReceived 30 November 1998; published in the issue dated 14 June 1999 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 e+e- 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. © 1999 The American Physical Society URL:
