Query: Ratios of dijet production cross sections as a function of the absolute
  difference in rapidity between jets in proton-proton collisions at sqrt(s) =
  7 TeV   A study of dijet production in proton-proton collisions was performed at
sqrt(s) = 7 TeV for jets with pt > 35 GeV and abs(y) < 4.7 using data collected
with the CMS detector at the LHC in 2010. Events with at least one pair of jets
are denoted as "inclusive". Events with exactly one pair of jets are called
"exclusive". The ratio of the cross section of all pairwise combinations of
jets to the exclusive dijet cross section as a function of the rapidity
difference between jets abs(Delta(y)) is measured for the first time up to
abs(Delta(y)) = 9.2. The ratio of the cross section for the pair consisting of
the most forward and the most backward jet from the inclusive sample to the
exclusive dijet cross section is also presented. The predictions of the Monte
Carlo event generators PYTHIA6 and PYTHIA8 agree with the measurements. In both
ratios the HERWIG++ generator exhibits a more pronounced rise versus
abs(Delta(y)) than observed in the data. The BFKL-motivated generators CASCADE
and HEJ+ARIADNE predict for these ratios a significantly stronger rise than
observed.
