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…
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…
Accessing proton GPDs in asymmetric frames: Numerical implementation
Martha Constantinou, Shohini Bhattacharya, Krzysztof Cichy +7
In this work, we present a numerical investigation of a novel Lorentz-covariant parametrization to extract -dependent GPDs using off-forward matrix elements of momentum-boosted…
Generalized Parton Distributions from Lattice QCD with Asymmetric Momentum Transfer: Unpolarized Quarks
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +7
Traditionally, lattice QCD computations of generalized parton distributions (GPDs) have been carried out in a symmetric frame, where the transferred momentum is symmetrically distr…
First Lattice QCD Study of Proton Twist-3 GPDs
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +4
We present first results on selected twist-3 quark GPDs using the quasi-distribution method. This approach relates lattice QCD data and light-cone distribution functions using Larg…
