Description:
    A measurement is presented of the triple-differential dijet cross section at a centre-of-mass
    energy of 8 TeV using 19.7 fb$^-1$ of data collected with the CMS detector in
    proton-proton collisions at the LHC. The cross section is measured as a function of the
    average transverse momentum, half the rapidity separation, and the boost of the two
    leading jets in the event. The cross section is corrected for detector effects and compared
    to calculations in perturbative quantum chromodynamics at next-to-leading order
    accuracy, complemented with electroweak and nonperturbative corrections. New
    constraints on parton distribution functions are obtained and the inferred value of the
    strong coupling constant is $\alpha_s(M_{Z})$ = 0.1199 $\pm$ 0.0015 (exp)$^{+0.0031}_{-0.0020}$ (theo),
    where M$_{Z}$ is the mass of the Z boson.
