Off-forward parton distributions [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 1998
Recently, there have been some interesting developments involving off-forward parton distributions of the nucleon, deeply virtual Compton scattering, and hard diffractive vector-meson production. These developments are triggered by the realization that the off-forward distributions contain information about the internal spin structure of the nucleon ...

Parton Shower based on TMD parton distributions

open access: yes, 2019
We present a parton shower based on Transverse Momentum Dependent (TMD)parton distributions obtained with the Parton Branching method. We investigatehow well the TMD parton shower reproduces the TMD parton distributions.Applications of the TMD parton ...

Double parton distributions: An introduction

open access: yes, 2021
In factorization theorems for double parton scattering (DPS) the non-perturbative parts of the cross section are encoded in universal functions, double parton distributions (DPDs) in the case of collinear factorization and double transverse momentum ...

A quantitative study of two-loop splitting in double parton distributions

open access: yesJournal of High Energy Physics
Double parton distributions at small distances between the two partons are dominated by a mechanism in which the two observed partons originate from the splitting of a single parton.

Evolution of colour correlated double parton distributions: a quantitative study

open access: yesJournal of High Energy Physics
Double parton distributions satisfy the same evolution equations as ordinary single-parton densities, provided that the colours of the two partons are uncorrelated.

Proton Spin Structure from Measurable Parton Distributions

open access: yes, 2012
We present a systematic study of the proton spin structure in terms of measurable parton distributions. For a transversely polarized proton, we derive a polarization sum rule from the leading generalized parton distributions appearing in hard exclusive ...

Probing Spin Dependent Quark and Gluon Distributions Through Azimuthal and Polarization Asymmetries

open access: yesEPJ Web of Conferences, 2016
Spin and transverse momentum dependent parton distributions - Generalized Parton Distributions, Transverse Momentum Distributions and related distributions - are at the interface between the QCD structure of the hadrons and observable quantities.

Nonperturbative evolution of parton quasi-distributions

open access: yesPhysics Letters B, 2017
Using the formalism of parton virtuality distribution functions (VDFs) we establish a connection between the transverse momentum dependent distributions (TMDs) F(x,k⊥2) and quasi-distributions (PQDs) Q(y,p3) introduced recently by X.

Endpoint singularities in unintegrated parton distributions

open access: yes, 2007
We examine the singular behavior from the endpoint region x → 1 in parton distributions unintegrated in both longitudinal and transverse momenta. We identify and regularize the singularities by using the subtraction method, and compare this with the cut ...
