Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

This handbook provides a comprehensive review of transverse-momentum-dependent
parton distribution functions and fragmentation functions, commonly referred to as …

A bstract A number of important observables exhibit logarithms in their perturbative
description that are induced by emissions at widely separated rapidities. These include …

A bstract We compute the quark and gluon transverse momentum dependent parton
distribution functions at next-to-next-to-next-to-leading order (N 3 LO) in perturbative QCD …

A bstract We consider Drell-Yan production pp→ V* X→ LX at small q T≪ Q, where q T and
Q are the total transverse momentum and invariant mass of the leptonic final state L …

A bstract Differential measurements of the semi-inclusive deep inelastic scattering (SIDIS)
process with polarized beams provide important information on the three-dimensional …

A bstract We derive and analytically solve renormalization group (RG) equations of gauge
invariant non-local Wilson line operators which resum logarithms for event shape …

A bstract We continue the study of power corrections for N-jettiness subtractions by
analytically computing the complete next-to-leading power corrections at\(\mathcal {O}\left …

A bstract We derive and solve renormalization group equations that allow for the
resummation of subleading power rapidity logarithms. Our equations involve operator …

A bstract Perturbative cross-sections in QCD are beset by logarithms of kinematic invariants,
whose arguments vanish when heavy particles are produced near threshold. Contributions …
