Nucleon axial and pseudoscalar form factors from lattice QCD at the physical point
C. Alexandrou, S. Bacchio, M. Constantinou +8
We compute the nucleon axial and induced pseudoscalar form factors using three ensembles of gauge configurations, generated with dynamical light quarks with mass tuned to approxima…
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…
The x-dependence of hadronic parton distributions: A review on the progress of lattice QCD
Martha Constantinou
In this article, we review recent lattice calculations on the -dependence of parton distributions, with the latter providing information on hadron structure. These calculations…
The Mellin moments and for the pion and kaon from lattice QCD
Constantia Alexandrou, Simone Bacchio, Ian Cloet +4
We present a calculation of the pion quark momentum fraction, , and its third Mellin moment . We also obtain directly, for the first time, $…
Confronting lattice parton distributions with global QCD analysis
J. Bringewatt, N. Sato, W. Melnitchouk +3
We present the first Monte Carlo based global QCD analysis of spin-averaged and spin-dependent parton distribution functions (PDFs) that includes nucleon isovector matrix elements…
Flavor decomposition for the proton helicity parton distribution functions
C. Alexandrou, M. Constantinou, K. Hadjiyiannakou +2
We present, for the first time, an \textit{ab initio} calculation of the individual up, down and strange quark helicity parton distribution functions for the proton. The calculatio…
