Abstract (data abstract)
CERN-LHC. Measurement of dijet angular distributions from the first LHC PP collisions at a centre-of-mass energy of 7 TeV. The data sample has an integrated luminosity of 3.1 pb-1 and dijet angular distributions and centrality ratios are measured up to a dijet mass of 2.8 TeV. The angular distributions are presented in the form of the variable CHI=exp(y_1-y_2) where y_1,2 are the rapidities of the two leading jets. The centrality ratio is the ratio between the number of events with both jets in the absolute pseusdorapidity range 0.0 to 0.7 to the number with both jets in the range 0.7 to 1.3. In the tables both the measured data with statistical errors and the QCD predictions with systematic uncertainties are listed. Numerical values were supplied by Henri Bachacou.
