Résumé |
The light-cone definition of Parton Distribution Functions (PDFs) does not allow for a direct ab
initio determination employing methods of Lattice QCD simulations that naturally take place in
Euclidean spacetime. In this presentation we focus on pseudo-PDFs where the starting point
is the equal time hadronic matrix element with the quark and anti-quark fields separated by a
finite distance. We focus on Ioffe-time distributions, which are functions of the Ioffe-time
$\nu$, and can be understood as the Fourier transforms of parton distribution functions with
respect to the momentum fraction variable $x$. We present lattice results for the case of the
nucleon and we also perform a comparison with the pertinent phenomenological
determinations. |
