Gauge-invariant TMD factorization for Drell-Yan hadronic tensor at small x
Ian Balitsky
The Drell-Yan hadronic tensor for electromagnetic (EM) current is calculated in the Sudakov region with accuracy, first at the tree level and…
Collinear Factorization at sub-asymptotic kinematics and validation in a diquark spectator model
Juan V. Guerrero, Alberto Accardi
We revisit the derivation of collinear factorization for Deep Inelastic Scattering at sub-asymptotic values of the four momentum transfer squared, where the masses of the particles…
Neural-network analysis of Parton Distribution Functions from Ioffe-time pseudodistributions
Luigi Del Debbio, Tommaso Giani, Joseph Karpie +3
We extract two nonsinglet nucleon Parton Distribution Functions from lattice QCD data for reduced Ioffe-time pseudodistributions. We perform such analysis within the NNPDF framewor…
Transverse moments of TMD parton densities and ultraviolet divergences
Ted Rogers
I review some open questions relating to the large transverse momentum divergences in transverse moments of transverse momentum dependent (TMD) parton correlation func- tions. I al…
Short-Range Correlations and the Nuclear EMC Effect in Deuterium and Helium-3
E. P. Segarra, J. R. Pybus, F. Hauenstein +7
The EMC effect in deuterium and helium-3 is studied using a convolution formalism that allows isolating the impact of high-momentum nucleons in short-ranged correlated (SRC) pairs.…
Parton distributions and lattice QCD calculations: toward 3D structure
Martha Constantinou, Aurore Courtoy, Markus A. Ebert +24
The strong force which binds hadrons is described by the theory of Quantum Chromodynamics (QCD). Determining the character and manifestations of QCD is one of the most important an…
