Unveiling generalized parton distributions through the pseudo-distribution approach
Niilo Nurminen, Shohini Bhattacharya, Wojciech Chomicki +4
Understanding the intricate three-dimensional internal structure of the nucleon has been a long-standing challenge. The main quantitative tool to map out this structure are the gen…
Generalized Parton Distributions from Lattice QCD with Asymmetric Momentum Transfer: Axial-vector case
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +8
Recently, we made significant advancements in improving the computational efficiency of lattice QCD calculations for Generalized Parton Distributions (GPDs). This progress was achi…
Chiral-even axial twist-3 GPDs of the proton from lattice QCD
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +4
This work presents the first lattice-QCD calculation of the twist-3 axial quark GPDs for the proton using the large-momentum effective theory approach. We calculate matrix elements…
Moments of proton GPDs from the OPE of nonlocal quark bilinears up to NNLO
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +7
For the first time, we present a lattice QCD determination of Mellin moments of unpolarized generalized parton distributions (GPDs) of the proton from an analysis of the quasi-GPD…
Generalized Parton Distributions from Lattice QCD
Krzysztof Cichy, Shohini Bhattacharya, Martha Constantinou +8
In recent years, there has been a breakthrough in lattice calculations of -dependent partonic distributions. This encompasses also distributions describing the 3D structure of t…
GPDs in asymmetric frames
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +7
It is often taken for granted that Generalized Parton Distributions (GPDs) are defined in the "symmetric" frame, where the transferred momentum is symmetrically distributed between…
