An Axial : UV Completion and Experimental Searches
Rundong Fang, Jinhui Guo, Ming Li +3
We propose an anomaly-free and renormalizable axial model and study its experimental signatures for masses from the MeV scale to the TeV scale. The opposite…
Orbital angular momentum at small in the large limit
G. Zardo Becker, Yuri V. Kovchegov, Ming Li +2
We extend the small- analysis of the quark and gluon orbital angular momentum (OAM) distributions in the proton from the large- limit considered in our earlier works to the…
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 Weizsäc…
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…
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…
