Generalized Parton Distributions from Lattice QCD with Asymmetric Momentum Transfer: Tensor Case
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +4
The calculation of generalized parton distributions (GPDs) in lattice QCD was traditionally done by calculating matrix elements in the symmetric frame. Recent advancements have sig…

Generalized Parton Distributions from Lattice QCD with Asymmetric Momentum Transfer: Unpolarized Quarks at Nonzero Skewness
Min-Huan Chu, Manuel Colaço, Shohini Bhattacharya +4
We extend the formalism of asymmetric frames of reference for generalized parton distributions (GPDs) to the case of nonzero skewness, i.e., including longitudinal momentum transfe…

Moments of Axial-Vector GPD from Lattice QCD: Quark Helicity, Orbital Angular Momentum, and Spin-Orbit Correlation
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +7
In this work, we present a lattice QCD calculation of the Mellin moments of the twist-2 axial-vector generalized parton distribution (GPD), , at zero skewnes…
