Abstract: (arXiv)
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 cut-off scale. In this work, we study the associated production of the gravitons with a ZZ boson or a photon at e+ee^+ e^- colliders of energies of LEPII to the Next Linear Colliders (NLC) (s=0.251.5\sqrt{s}=0.25-1.5 TeV) and calculate the sensitivity to the new interactions. We also obtain the limit on the cut-off scale using the present data from LEPII.
