Bayesian-Wilson coefficients in lattice QCD computations of valence PDFs and GPDs
Nikhil Karthik, Raza Sabbir Sufian
We propose an analysis method for the leading-twist operator product expansion based lattice QCD determinations of the valence parton distribution function (PDF). In the first step…
Towards studying the structural differences between the pion and its radial excitation
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…
Quark distribution inside a pion in many-flavor (2 + 1)-dimensional QCD using lattice computations: UV listens to IR
Nikhil Karthik
We study the changes in the short-distance quark structure of the Nambu-Goldstone boson when the long-distance symmetry-breaking scales are depleted controllably. We achieve this b…
QED-inspired three-dimensional conformal lattice gauge theory without fine-tuning
Nikhil Karthik, Rajamani Narayanan
We construct a conformal lattice theory with only gauge degrees of freedom based on the induced non-local gauge action in QED coupled to large number of flavors of massless…
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…
