  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 $p_\mathrm{T}$ $\gt$ 35 GeV and rapidity $\vert y\vert$ $\lt$ 4.7.
Various dijet production cross section ratios are also measured. A veto on
additional jets with $p_\mathrm{T}$ $\gt$ 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.
