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…
