摘要
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 (Formula presented) boson or a photon at (Formula presented) colliders of energies of the CERN LEPII to the Next Linear Colliders (Formula presented) 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.
