Infrared sensitivity of single jet inclusive production at hadron colliders

Understand

Jet production at hadron colliders is a benchmark process to probe the dynamics of the strong interaction and the structure of the colliding hadrons.

• One of the most basic jet production observables is the single jet inclusive cross section, which is obtained by summing all jets that are observed in an event.
• Our recent computation of next-to-next-to-leading order (NNLO) QCD contributions to single jet inclusive observables uncovered large corrections in certain kinematical regions, which also resulted in a sizeable ambiguity on the appropriate choice of renormalization and factorization scales.
• We now perform a detailed investigation of the infrared sensitivity of the different ingredients to the single jet inclusive cross section.
