Looking for Large Extra Dimensions in the Early LHC Data

Abstract

We explore the opportunity to look for large extra dimensions in the early stages of the LHC running. The high-E${}_T$ dijet production is analyzed via a novel kinematic variable when the machine center-of-mass energy varies from 7 TeV through 10 TeV to 14 TeV and the accumulated data range from 0.5 to 8 fb${}^{-1}$. The estimations of the reach in the effective scale $M_S$ for different numbers of large extra dimensions are presented.
