Testing TeV Scale Quantum Gravity using Dijet Production at the Tevatron

Abstract

Dijet production at the Tevatron including effects of virtual exchanges of spin-2 Kaluza-Klein modes in theories with large extra dimensions is considered. The experimental dijet mass and angular distribution are exploited to obtain stringent limits ($\sim 1.2$ TeV) on the effective string scale $M_S$.

The solid histogram shows the SM NLO prediction; dashed histograms show the prediction for $M_S=800$ GeV and 1 TeV (upper line and lower line, respectively.) Data are taken from the D0 collaboration.
