Seeking TeV-Scale Quantum Gravity at an $e{\hat{I}}^3$ collider

Abstract

Theories with large extra compact dimensions predict exciting phenomenological consequences at the TeV scale. Such theories can, consequently, be tested/verified in experiments at future colliders like the Next Linear Collider (NLC). In this paper, we study the production of the spin-2 Kaluza-Klein excitations in NLC operating in the $e{\hat{I}}^3$ mode. Results for unpolarised and polarised cases are presented and it is shown that it is possible to use this process to test these theories to values of the effective string scale between about 1 - 7 TeV.
