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…
Gluon PDF of the proton using twisted mass fermions
Joseph Delmar, Constantia Alexandrou, Krzysztof Cichy +2
In this paper, we present lattice QCD results for the -dependence of the unpolarized gluon PDF for the proton. We use one ensemble of maximally twisted mass fermions…
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…
Nonperturbative renormalization of asymmetric staple-shaped operators in twisted mass lattice QCD
Constantia Alexandrou, Simone Bacchio, Krzysztof Cichy +8
Staple-shaped Wilson line operators are necessary for the study of transverse momentum-dependent parton distribution functions (TMDPDFs) in lattice QCD and beyond. In this work, we…
