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…

Helicity Evolution at Small : Quark to Gluon and Gluon to Quark Transition Operators
Jeremy Borden, Yuri V. Kovchegov, Ming Li
We include the quark to gluon and gluon to quark shock-wave transition operators into the small Bjorken- evolution equations for helicity in the flavor-singlet channel derived e…
