Top quark phenomenology of the ADD model and the minimal length scenario
Top quark phenomenology of the ADD model and the minimal length scenario
We study top-(anti)quark pair production at the Tevatron and Large Hadron Collider in the context of the minimal length scenario of the Arkani-Hamed, Dimopoulos and Dvali model of extra dimensions. We show that sizable effects onto both the integrated and differential cross section due to graviton mediation are expected for a string scale, MS, of Ô(1–10 TeV) and several extra dimensions, δ, all compatible with current experimental constraints. Potential limits on MS are extracted. We also highlight clear phenomenological differences between a simple Arkani-Hamed, Dimopoulos and Dvali scenario and its modification based on using the minimal length scenario as a natural regulator for divergent amplitudes of virtual KK graviton exchange.

Abstract
We study top-(anti)quark pair production at the Tevatron and Large Hadron Collider in the context of the minimal length scenario of the Arkani-Hamed, Dimopoulos and Dvali model of extra dimensions. We show that sizable effects onto both the integrated and differential cross section due to graviton mediation are expected for a string scale, MS, of Ô(1–10 TeV) and several extra dimensions, δ, all compatible with current experimental constraints. Potential limits on MS are extracted. We also highlight clear phenomenological differences between a simple Arkani-Hamed, Dimopoulos and Dvali scenario and its modification based on using the minimal length scenario as a natural regulator for divergent amplitudes of virtual KK graviton exchange.
