Description
We determine the complete spin and momentum fraction decomposition of the nucleon at the continuum limit and compare with phenomenological analyses.
The computation is done using four twisted mass ensembles with different lattice spacings and physical pion mass.
The renormalization functions are computed fully non-perturbatively including the mixing between the singlet quark and gluon operators.
In addition, we present preliminary results on the gravitational form factors as a function of the momentum transfer square for the same ensembles.
