Testing the Scale Dependence of the Scale Factor in Double Dijet Production at the LHC

Understand

The scale factor is the effective cross section used to characterize the measured rate of inclusive double dijet production in high energy hadron collisions.

• It is sensitive to the two-parton distributions in the hadronic projectile.
• In principle, the scale factor depends on the center of mass energy and on the minimal transverse energy of the jets contributing to the double dijet cross section.
• Here, we point out that proton-proton collisions at the LHC will provide for the first time experimental access to these scale dependences in a logarithmically wide, nominally perturbative kinematic range of minimal transverse energy between 10 GeV and 100 GeV.
