Nonlocal chiral anomaly and generalized parton distributions
Shohini Bhattacharya, Yoshitaka Hatta, Jakob Schoenleber
We discuss the nonlocal generalization of the QCD chiral anomaly along the light-cone and derive relations between twist-two, twist-three and twist-four generalized parton distribu…

Exploring orbital angular momentum and spin-orbit correlation for gluons at the Electron-Ion Collider
Shohini Bhattacharya, Renaud Boussarie, Yoshitaka Hatta
In our previous work [Phys. Rev. Lett. 128, 182002 (2022)], we introduced a pioneering observable aimed at experimentally detecting the orbital angular momentum (OAM) of gluons. Ou…

Spin-orbit entanglement in the Color Glass Condensate
Shohini Bhattacharya, Renaud Boussarie, Yoshitaka Hatta
We compute the spin-orbit correlations of quarks and gluons at small- and show that the helicity and the orbital angular momentum of individual partons are strongly anti-aligned…
