The event sample, recorded with the CMS detector, corresponds to an integrated luminosity of 36  pb-1. The data are found to be in good agreement with the predictions of perturbative QCD, and yield no evidence of quark compositeness. With a modified frequentist approach, a lower limit on the contact interaction scale for left-handed quarks of Λ+=5.6  TeV (Λ-=6.7  TeV) for destructive (constructive) interference is obtained at the 95% confidence level.
