Description

We compute the top quark threshold contributions to the $\gamma \gamma$ production at the LHC. These contributions become significant when the invariant mass of the photon pair, $M_{\gamma \gamma }$ just exceeds two times the mass of the top quark and induce some features in the $M_{\gamma \gamma }$ distribution. We determine the magnitude of this threshold effect and investigate other kinematic cuts which may enhance its significance.
