Measurement of the differential dijet production cross section in proton-proton collisions at sqrt(s)=7 TeV

TL;DR

This paper reports a measurement of the inclusive dijet production cross section in proton-proton collisions at 7 TeV, covering a wide mass and rapidity range, and compares the results with QCD predictions.

Contribution

First measurement of the double-differential inclusive dijet cross section at 7 TeV covering a broad mass and rapidity range with CMS detector data.

Findings

Data agrees well with next-to-leading-order QCD predictions.

Provides detailed cross section measurements up to 3.5 TeV dijet mass.

Extends previous measurements to higher mass and rapidity regions.

Abstract

A measurement of the double-differential inclusive dijet production cross section in proton-proton collisions at sqrt(s)=7 TeV is presented as a function of the dijet invariant mass and jet rapidity. The data correspond to an integrated luminosity of 36 inverse picobarns, recorded with the CMS detector at the LHC. The measurement covers the dijet mass range 0.2 TeV to 3.5 TeV and jet rapidities up to |y|=2.5. It is found to be in good agreement with next-to-leading-order QCD predictions.
