| dc.description | 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 diphoton production in $γγ$, $p\bar p$, and $e^+ e^-$ collisions in the model of low scale gravity. Since in the standard model photon-photon scattering only occurs via box diagrams, the cross section is highly suppressed. Thus, photon-photon scattering opens an interesting opportunity for studying the new gravity interaction, which allows tree-level photon couplings. In addition, we also examine the diphoton production at hadronic and $e^+ e^-$ colliders. We derive the limits on the cut-off scale from the available diphoton data and also estimate the sensitivity reach in Run II at the Tevaton and at the future linear $e^+ e^-$ colliders. | |
