Recent results on unintegrated parton distributions
Francesco Hautmann,Hannes Jung +1 more
TL;DR: In this paper, the use of u-pdf's in the Monte-Carlo simulation of hadronic final states at high-energy colliders is discussed, and it is shown that the U-pdfs can be characterized with precision in terms of nonlocal operator matrix elements.
Journal ArticleDOI
On the use of the KMR unintegrated parton distribution functions
TL;DR: In this article, the authors demonstrate numerically that the commonly used differential definition of the UPDFs leads to erroneous results for large transverse momenta and identify the reason for that, being the use of the ordinary PDFs instead of the cutoff dependent distribution functions.

An effective field theory approach to quarkonium at small transverse momentum
TL;DR: In this article, effective field theory was applied to observables in quarkonium production and decay that are sensitive to soft gluon radiation, in particular measurements that were sensitive to small transverse momentum.

Transverse momentum in double parton scattering: factorisation, evolution and matching
TL;DR: In this paper, the authors give a description of double parton scattering with measured transverse momenta in the final state, extending the formalism for factorisation and resummation developed by Collins, Soper and Sterman for the production of colourless particles.
Journal ArticleDOI
Automated predictions from polarized matrix elements
TL;DR: In this article, the authors report the automation of polarized matrix element computations in the publicly available Monte Carlo tool suite, MadGraph5_aMC@NLO. This enables scattering and decay simulations involving helicitypolarized asymptotic or intermediate states, preserving both spin-correlation and off-shell effects.

Evolution of parton densities beyond leading order: The non-singlet case
TL;DR: In this paper, the authors developed a technique based explicitly on the factorization properties of mass singularities, which allows one to calculate the evolution of parton densities beyond leading order.

Parton Distribution and Decay Functions
John Collins,Davison E. Soper +1 more
TL;DR: In this paper, the authors define parton distribution and decay functions in QCD and prove some of their basic properties, such as renormalization, light-cone expansions and sum rules.
