QCD transverse-momentum resummation in gluon fusion processes
S. Catani, M. Grazzini
We consider the production of a generic system of non-strongly interacting particles with a high total invariant mass M in hadron collisions. We examine the transverse-momentum (q_…
Feynman's Tree Theorem and Loop-Tree Dualities
Isabella Bierenbaum, Stefano Catani, Petros Draggiotis +1
We discuss the duality theorem, which provides a relation between loop integrals and phase space integrals. We rederive the duality relation for the one-loop case and extend it to…
Production of Drell--Yan lepton pairs in hadron collisions: transverse-momentum resummation at next-to-next-to-leading logarithmic accuracy
G. Bozzi, S. Catani, G. Ferrera +2
We consider the transverse-momentum (q_T) distribution of Drell--Yan lepton pairs produced in hadron collisions. At small values of q_T, we resum the logarithmically-enhanced pertu…
A Tree-Loop Duality Relation at Two Loops and Beyond
Isabella Bierenbaum, Stefano Catani, Petros Draggiotis +1
The duality relation between one-loop integrals and phase-space integrals, developed in a previous work, is extended to higher-order loops. The duality relation is realized by a mo…
W boson production at hadron colliders: the lepton charge asymmetry in NNLO QCD
S. Catani, G. Ferrera, M. Grazzini
We consider the production of W bosons in hadron collisions, and the subsequent leptonic decay W->lnu_l. We study the asymmetry between the rapidity distributions of the charged le…
