Abstract (englisch):

The decorrelation in the azimuthal angle between the most forward and the most backward jets (Mueller-Navelet jets) is measured in data collected in pp collisions with the CMS detector at the LHC at s = 7 s√=7 TeV. The measurement is presented in the form of distributions of azimuthal-angle differences, Δϕ, between the Mueller-Navelet jets, the average cosines of ( π − Δ ϕ ), 2( π − Δ ϕ ), and 3( π − Δ ϕ ), and ratios of these cosines. The jets are required to have transverse momenta, p T , in excess of 35 GeV and rapidities, | y |, of less than 4.7. The results are presented as a function of the rapidity separation, Δ y , between the Mueller-Navelet jets, reaching Δ y up to 9.4 for the first time. The results are compared to predictions of various Monte Carlo event generators and to analytical predictions based on the DGLAP and BFKL parton evolution schemes.
