Positivity and renormalization of parton densities

There have been recent debates about whether \(\overline{\text{MS}}\) parton densities exactly obey positivity bounds (including the Soffer bound), and whether the bounds should be applied as a constraint on global fits to parton densities and on nonperturbative calculations. A recent paper (JHEP \(...
