Universality of transverse-momentum resummation and hard factors at the NNLO
S. Catani, L. Cieri, D. de Florian +2
We consider QCD radiative corrections to the production of colourless high-mass systems in hadron collisions. The logarithmically-enhanced contributions at small transverse momentu…
Isolating Prompt Photons with Narrow Cones
Stefano Catani, Michel Fontannaz, Jean-Philippe Guillet +1
We discuss the isolation of prompt photons in hadronic collisions by means of narrow isolation cones and the QCD computation of the corresponding cross sections. We reconsider the…
Soft-gluon resummation for single-particle inclusive hadroproduction at high transverse momentum
S. Catani, M. Grazzini, A. Torre
We consider the cross section for one-particle inclusive production at high transverse momentum in hadronic collisions. We present the all-order resummation formula that controls t…
