Study of dijet events with large rapidity separation in proton-proton collisions at $\sqrt{s}=$ 2.76 TeV

Abstract

The cross sections for inclusive and Mueller-Navelet dijet production are measured as a function of the rapidity separation between the jets in proton-proton collisions at $\sqrt{s}=$ 2.76 TeV for jets with transverse momentum $p_{\mathrm{T}}$ $>$ 35 GeV and rapidity $|y|$ $<$ 4.7. Various dijet production cross section ratios are also measured. A veto on additional jets with $p_{\mathrm{T}}$ $>$ 20 GeV is introduced to improve the sensitivity to the effects of the Balitsky-Fadin-Kuraev-Lipatov (BFKL) evolution. The measurement is compared with the predictions of various Monte Carlo models based on leading-order and next-to-leading-order calculations including the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi leading-logarithm (LL) parton shower as well as the LL BFKL resummation.
