Constraining Large Extra Dimensions Using Dilepton Data from the Tevatron Collider

Abstract

We use the invariant mass distribution of Drell-Yan dileptons as measured by the CDF and D0 Collaborations at the Fermilab Tevatron and make a careful analysis to constrain Kaluza-Klein models with large extra dimensions. The combined data from both collaborations lead to a conservative lower bound on the string scale M_S of about 1 TeV at 95% confidence level.
