Quark pseudodistributions at short distances

Physics Letters B, 2018
We perform a one-loop study of the small-z32 behavior of the Ioffe-time distribution (ITD) M(ν,z32), the basic function that may be converted into parton pseudo- and quasi-distributions.

Sheaves of nonlinear generalized functions and manifold-valued distributions

, 2009
This paper is part of an ongoing program to develop a theory of generalized differential geometry. We consider the space G[X,Y] of Colombeau generalized functions defined on a manifold X and taking values in a manifold Y. This space is essential in order

Updated flexible global parametrization of generalized parton distributions from elastic and deep inelastic inclusive scattering data

European Physical Journal C: Particles and Fields
An updated flexible parametrization of the generalized parton distributions in the quark, antiquark and gluon sectors is presented using constraints from high precision electron nucleon deep inelastic scattering data, from the u and d flavor separated ...

Measurement of the beam spin asymmetry of e→p→e′p′η in the deep-inelastic regime with CLAS

Physics Letters B, 2019
The beam spin asymmetry of the exclusive pseudoscalar channel e→p→e′p′η was measured for the first time in the deep-inelastic regime (W>2 GeV/c2 and Q2>1 GeV2/c2) using a longitudinally polarized 5.78 GeV electron beam at Jefferson Lab with the CEBAF ...

Generalized parton distributions in full lattice QCD

, 2005
We present recent results on generalized parton distributions from dynamical lattice QCD calculations. Our set of twelve different combinations of couplings and quark masses allows for a preliminary study of the pion mass dependence of the transverse ...

The exclusive limit of the pion-induced Drell–Yan process

Physics Letters B, 2015
Based on previous studies of hard exclusive leptoproduction of pions in which the essential role of the pion pole and the transversity generalized parton distributions (GPDs) has been pointed out, we present predictions for the four partial cross ...

From form factors to generalized parton distributions

, 2013
I present an extraction of generalized parton distributions from selected data on the electromagnetic nucleon form factors. The extracted distributions can in particular be used to quantify the contribution to the proton spin from the total angular ...

A set of generalized parton distributions [PDF]

, 2013
The information about generalized parton distributions (GPDs) extracted from exclusive meson leptoproduction (DVMP) within the handbag approach is summarized. Details are only discussed for the GPD E and the transversity ones.
