Evolution of colour correlated double parton distributions: a quantitative study
Journal of High Energy PhysicsDouble parton distributions satisfy the same evolution equations as ordinary single-parton densities, provided that the colours of the two partons are uncorrelated.

Tensor-polarized parton density in the N→Δ transition
Physics Letters BThe generalized parton distributions for transitions between baryon states with different masses have a forward limit in which they behave as parton densities (light-front momentum transfer Δ+,ΔT=0, energy transfer Δ−≠0).

The ALARIC parton shower [PDF]
EPJ Web of ConferencesParton showers are important tools in the event generation chain for present and future colliders. Recently, their formally achieved accuracy has been under extended scrutiny.

Hadron structure beyond collinear level and precision DIS measurements
EPJ Web of Conferences, 2015 General formulations of QCD factorization for hadronic collisions extend the notion of ordinary parton distributions to transverse-momentum dependent (TMD) parton density and parton decay functions.

Double parton scattering: A study of the effective cross section within a Light-Front quark model
Physics Letters B, 2016 We present a calculation of the effective cross section σeff, an important ingredient in the description of double parton scattering in proton–proton collisions.

Generalized parton correlation functions for a spin-1/2 hadron
, 2009 The fully unintegrated, off-diagonal quark-quark correlator for a spin-1/2 hadron is parameterized in terms of so-called generalized parton correlation functions.

Can We Measure Parton-Parton Cross Sections? [PDF]
Physical Review D, 1973 Multiple-core production in hadron-hadron collisions directly measures (in the context of the parton model) differential cross sections for parton-parton collisions. To obtain \ensuremath{\sim}20% accuracy in reconstruction of the parton-parton kinematics requires transverse momentum of the cores \ensuremath{\gtrsim} 5 GeV/c. Experiments at NAL as well

Covariant extension of the GPD overlap representation at low Fock states
European Physical Journal C: Particles and Fields, 2017 We present a novel approach to compute generalized parton distributions within the lightfront wave function overlap framework. We show how to systematically extend generalized parton distributions computed within the DGLAP region to the ERBL one ...

GR@PPA 2.9: radiation matching for simulating photon production processes in hadron collisions
, 2018 We release an event generator package, GR@PPA 2.9, for simulating the direct (single) photon and diphoton (double photon) production in hadron collisions.
