Abstract
The cross section for dijet production in proton-proton collisions at √s=7 TeV is presented as a function of ˜ξ,
a variable that approximates the fractional momentum loss of the
scattered proton in single-diffractive events. The analysis is based on
an integrated luminosity of 2.7 nb−1
collected with the CMS detector at the LHC at low instantaneous
luminosities, and uses events with jet transverse momentum of at least
20 GeV. The dijet cross section results are compared to the predictions
of diffractive and nondiffractive models. The low-˜ξ
data show a significant contribution from diffractive dijet production,
observed for the first time at the LHC. The associated rapidity gap
survival probability is estimated.
