Findings

Reliable missing transverse energy measurements are crucial.

Initial- and final-state radiation significantly affect signal-background discrimination.

Squark pair production could be observable with early LHC data.

Abstract

We examine the ability of LHC experiments to observe jets from squark pair production at the center-of-mass energy E$_{CM}$=10 TeV and 1 fb$^{-1}$ of integrated luminosity. We point out the crucial influence of initial- and final-state radiation on the signal/background discriminating ability of different kinematic variables. The reliable measurements of missing transverse energy and stransverse mass would play a key role in picking out the signal against the background.
