Abstract
Gravity can become strong at the TeV scale in the theory of extra dimensions. An effective Lagrangian can be used to describe the gravitational interactions below a cutoff scale. In this work, we study the associated production of the gravitons with a Z boson or a photon at e + e - colliders of energies of the CERN LEPII to the Next Linear Colliders (√s=0.25-1.5 TeV) and calculate the sensitivity to the new interactions. We also obtain the limit on the cutoff scale using the present data from LEPII. ©1999 The American Physical Society.
