Parton distribution functions of $Î^+$ on the lattice
arXiv:1907.09827
Abstract
We present results for renormalized matrix elements related to the unpolarized quasi-distribution function of the $Î^+$ baryon making use of the large momentum effective theory. Two ensembles of $N_f=2+1+1$ twisted mass fermions with a clover term and pion masses of 250 MeV and 330 MeV are analyzed. We employ momentum smearing to improve the overlap with the boosted $Î$ state significantly reducing in this way the statistical error of both two- and three-point functions.
