Overview

abstract

  • Abstract; A measurement of the dijet production cross section is reported based on proton–proton collision data collected in 2016 at ; ; $$sqrt{s}=13,text {Te}hspace{-.08em}text {V} $$; ; ; ; s; ; =; 13; ; Te; ; V; ; ; ; by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of up to 36.3; ; $$,text {fb}^{-1}$$; ; ; ; ; ; fb; ; ; -; 1; ; ; ; ; ; . Jets are reconstructed with the anti-; ; $$k_{textrm{T}} $$; ; ; k; T; ; ; ; algorithm for distance parameters of ; ; $$R=0.4$$; ; ; R; =; 0.4; ; ; ; and 0.8. Cross sections are measured double-differentially (2D) as a function of the largest absolute rapidity ; ; $$-y -_{text {max}} $$; ; ; ; -; y; -; ; max; ; ; ; of the two jets with the highest transverse momenta ; ; $$p_{textrm{T}}$$; ; ; p; T; ; ; ; and their invariant mass ; ; $$m_{1,2} $$; ; ; m; ; 1; ,; 2; ; ; ; ; , and triple-differentially (3D) as a function of the rapidity separation ; ; $$y^{*} $$; ; ; y; ; ; ; ; ; ; ; , the total boost ; ; $$y_{text {b}} $$; ; ; y; b; ; ; ; , and either ; ; $$m_{1,2} $$; ; ; m; ; 1; ,; 2; ; ; ; ; or the average ; ; $$p_{textrm{T}}$$; ; ; p; T; ; ; ; of the two jets. The cross sections are unfolded to correct for detector effects and are compared with fixed-order calculations derived at next-to-next-to-leading order in perturbative quantum chromodynamics. The impact of the measurements on the parton distribution functions and the strong coupling constant at the mass of the ; ; $${text {Z}} $$; ; Z; ; ; boson is investigated, yielding a value of ; ; $$alpha _textrm{S} (m_{{text {Z}}}) =0.1179pm 0.0019$$; ; ; ; α; S; ; ; (; ; m; Z; ; ); ; =; 0.1179; ±; 0.0019; ; ; ; .
