Nucleon average quark momentum fraction with $N_f=2+1$ Wilson fermions

Primary authors



We report on an analysis of the average quark momentum fraction of the nucleon and related quantities using $N_f=2+1$ Wilson fermions. Computations are performed on four CLS ensembles covering three values of the lattice spacing at pion masses down to $M_\pi \approx 200\,\mathrm{MeV}$. Several source-sink separations ($\sim 1.0\,\mathrm{fm}$ to $\sim 1.4\,\mathrm{fm}$) are used to assess excited-state contaminations. Preliminary results are shown for isovector quantities and the connected contribution to the isoscalar combination.
