Revealing chiral-odd two-meson generalized distribution amplitudes in reactions
Shohini Bhattacharya, Renaud Boussarie, Bernard Pire +1
We demonstrate that chiral-odd dimeson generalized distribution amplitudes (CO-GDAs) -- nonperturbative objects encoding the transition of a quark-antiquark pair into two mesons --…
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…
Probing quark orbital angular momentum at EIC and EicC
Shohini Bhattacharya, Duxin Zheng, Jian Zhou
We propose to detect signals from quark orbital angular momentum (OAM) through exclusive production in electron-(longitudinally-polarized) proton collisions. Our analysis dem…
