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…
Continuum-extrapolated NNLO Valence PDF of Pion at the Physical Point
Xiang Gao, Andrew D. Hanlon, Nikhil Karthik +7
We present lattice QCD calculations of valence parton distribution function (PDF) of pion employing next-to-next-leading-order (NNLO) perturbative QCD matching. Our calculations ar…
Pion distribution amplitude at the physical point using the leading-twist expansion of the quasi-distribution-amplitude matrix element
Xiang Gao, Andrew D. Hanlon, Nikhil Karthik +5
We present a lattice QCD determination of the distribution amplitude (DA) of the pion and the first few Mellin moments from an analysis of the quasi-DA matrix element within the le…
Lattice QCD Determination of the Bjorken- Dependence of Parton Distribution Functions at Next-to-next-to-leading Order
Xiang Gao, Andrew D. Hanlon, Swagato Mukherjee +4
We report the first lattice QCD calculation of pion valence quark distribution with next-to-next-to-leading order perturbative matching correction, which is done using two fine lat…

Xiang Gao, Nikhil Karthik, Swagato Mukherjee +3
We present an exploratory lattice QCD investigation of the differences between the valence quark structure of pion and its radial excitation in a fixed finite volume usin…

Xiang Gao, Nikhil Karthik, Swagato Mukherjee +3
We present our results on the electromagnetic form factor of pion over a wide range of using lattice QCD simulations with Wilson-clover valence quarks and HISQ sea quarks. We…
Valence parton distribution of pion from lattice QCD: Approaching continuum
Xiang Gao, Luchang Jin, Christos Kallidonis +6
We present a high-statistics lattice QCD determination of the valence parton distribution function (PDF) of the pion, with a mass of 300 MeV, using two very fine lattice spacings o…
Isovector parton distribution functions of the proton on a superfine lattice
Zhouyou Fan, Xiang Gao, Ruizi Li +7
We study isovector unpolarized and helicity parton distribution functions (PDF) of the proton within the framework of Large Momentum Effective Theory. We use a gauge ensemble, gene…
Pion valence quark PDF from lattice QCD
Charles Shugert, Xiang Gao, Taku Izubichi +7
We present lattice results on the valence-quark structure of the pion using a coordinate space method within the framework of Large Momentum Effective Theory (LaMET). In this metho…
