Higher Mellin Moments of the Unpolarized PDF of the Pion and the Kaon from Lattice QCD
Constantia Alexandrou, Simone Bacchio, Priyajit Jana +6
We present results on the Mellin moments of the unpolarized parton distribution function (PDF) of the pion and kaon up to the fourth order. The computation is done using one $N_f=2…
Generalized Parton Distributions from Lattice QCD with Asymmetric Momentum Transfer: Tensor Case
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +4
The calculation of generalized parton distributions (GPDs) in lattice QCD was traditionally done by calculating matrix elements in the symmetric frame. Recent advancements have sig…
Generalized Parton Distributions from Lattice QCD with Asymmetric Momentum Transfer: Unpolarized Quarks at Nonzero Skewness
Min-Huan Chu, Manuel Colaço, Shohini Bhattacharya +4
We extend the formalism of asymmetric frames of reference for generalized parton distributions (GPDs) to the case of nonzero skewness, i.e., including longitudinal momentum transfe…
Collins-Soper Kernel and Reduced Soft Function in Lattice QCD
Constantia Alexandrou, Simone Bacchio, Krzysztof Cichy +5
We evaluate the Collins-Soper kernel and the reduced soft function in lattice QCD, incorporating matching corrections. The calculation relies on the evaluation…
Quark and gluon momentum fractions in the pion and in the kaon
Constantia Alexandrou, Simone Bacchio, Martha Constantinou +9
We present results on the momentum fraction carried by quarks and gluons in the pion and the kaon. We employ three gauge ensembles generated with Wilson twisted-mass cl…
Moments of Axial-Vector GPD from Lattice QCD: Quark Helicity, Orbital Angular Momentum, and Spin-Orbit Correlation
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +7
In this work, we present a lattice QCD calculation of the Mellin moments of the twist-2 axial-vector generalized parton distribution (GPD), , at zero skewnes…
