Findings

Estimated reach in M_S for different extra dimension counts

Applicable to early LHC data with 0.5 to 8 fb^{-1}

Analysis across 7, 10, and 14 TeV energies

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.
