First study of polarized proton-proton scattering with small- $x$ helicity evolution

Daniel Adamiak, Nicholas Baldonado, Yuri V. Kovchegov +7

We perform a phenomenological study of helicity-dependent parton distribution functions (PDFs) using small- $x$ helicity evolution equations, incorporating for the first time single…

Helicity Evolution at Small $x$ : 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- $x$ evolution equations for helicity in the flavor-singlet channel derived e…

Gluon Double-Spin Asymmetry in the Longitudinally Polarized $p + p$ Collisions

Yuri V. Kovchegov, Ming Li

We derive the first-ever small- $x$ expression for the inclusive gluon production cross section in the central rapidity region of the longitudinally polarized proton-proton collisio…
