Unpolarized GPDs at small and non-zero skewness
Yuri V. Kovchegov, M. Gabriel Santiago, Huachen Sun
We study the small- asymptotics of unpolarized generalized parton distributions (GPDs) and generalized transverse momentum distributions (GTMDs). Unlike the previous works in th…
On the Two -Factors in the Small- Shockwave Formalism
Yuri V. Kovchegov, M. Gabriel Santiago, Huachen Sun
There are two -factors frequently used in the phenomenology of exclusive processes at small values of the Bjorken variable. One -factor takes into account the effects of…
Precision QCD with the Electron-Ion Collider
C. Alexandrou, M. Arratia, E. C. Aschenauer +66
This document summarizes the discussions at the program "Precision QCD with the Electron Ion Collider", held from May to June 2025 at the Institute for Nuclear Theory (INT) at the…
Analytic Solution for the Helicity Evolution Equations at Small and Large
Jeremy Borden, Yuri V. Kovchegov
We construct an exact analytic solution of the revised small- helicity evolution equations, where the contributions of the quark-to-gluon and gluon-to-quark transition operators…
Weizsäcker-Williams Gluon Helicity Distribution and Inclusive Dijet Production in Longitudinally Polarized Electron-Proton Collisions
Yuri V. Kovchegov, Ming Li
It is well-known that the back-to-back (correlation) limit of inclusive quark-antiquark dijet production in unpolarized high energy electron-proton collisions can probe the Weizsä…
First study of polarized proton-proton scattering with small- helicity evolution
Daniel Adamiak, Nicholas Baldonado, Yuri V. Kovchegov +7
We perform a phenomenological study of helicity-dependent parton distribution functions (PDFs) using small- helicity evolution equations, incorporating for the first time single…
