Abstract:

Recent results on jet production at forward pseudorapidities in collisions shed new light on some of the open questions of Quantum Chromodynamics (QCD). In particular, the measurement of the dijet cross section at large pseudorapidity intervals probes the yet little explored high-energy limit of QCD. In addition, the measurement of the inclusive jet cross section at extended pseudorapidities provides new information on the structure of the proton at large longitudinal momentum fractions. I will present the new measurements and discuss their implications for the relevant theoretical calculations and phenomenological models.
