Lattice continuum-limit study of nucleon quasi-PDFs
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +6
The quasi-PDF approach provides a path to computing parton distribution functions (PDFs) using lattice QCD. This approach requires matrix elements of a power-divergent operator in…
Unpolarized and helicity generalized parton distributions of the proton within lattice QCD
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
We present the first calculation of the -dependence of the proton generalized parton distributions (GPDs) within lattice QCD. Results are obtained for the isovector unpolarized…
The role of zero-mode contributions in the matching for the twist-3 PDFs and
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
The perturbative procedure of matching was proposed to connect parton quasi-distributions that are calculable in lattice QCD to the corresponding light-cone distributions which ent…
One-loop matching for the twist-3 parton distribution
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
Perturbative matching relates the parton quasi-distributions, defined by Euclidean correlators at finite hadron momenta, to the light-cone distributions which are accessible in exp…
Flavor non-singlet parton distribution functions from lattice QCD at physical quark masses via the pseudo-distribution approach
Manjunath Bhat, Krzysztof Cichy, Martha Constantinou +1
One of the great challenges of QCD is to determine the partonic structure of the nucleon from first principles. In this work, we provide such a determination of the flavor non-sing…
New insights on proton structure from lattice QCD: the twist-3 parton distribution function
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
In this work, we present the first-ever calculation of the isovector flavor combination of the twist-3 parton distribution function for the proton from lattice QCD. We use…
