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…

Gluon Double-Spin Asymmetry in the Longitudinally Polarized Collisions
Yuri V. Kovchegov, Ming Li
We derive the first-ever small- expression for the inclusive gluon production cross section in the central rapidity region of the longitudinally polarized proton-proton collisio…
