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” …

We give an overview of the theory for generalized parton distributions. Topics covered are
their general properties and physical interpretation, the possibility to explore the three …

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

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

In position space the interaction terms of soft-collinear effective theory must be multipole-
expanded to obtain interaction terms with homogeneous scaling behaviour. In this Letter we …

The N-jettiness observable TN provides a way of describing the leading singular behavior of
the N-jet cross section in the τ= TN/Q→ 0 limit, where Q is a hard interaction scale. We …

We study a Lagrangian formalism that avoids double counting in effective field theories
where distinct fields are used to describe different infrared momentum regions for the same …

A bstract It is by now well known that, at subleading power in scale ratios, factorization
theorems for high-energy cross sections and decay amplitudes contain endpoint-divergent …

Using the soft-collinear effective theory we derive the factorization theorem for the decays
B→ M 1 M 2 with M 1, 2= π, K, ρ, K*, at leading order in Λ/EM and Λ/mb. The results derived …

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