HadronRelated: It quantifies the dynamic quark-and-gluon content probed inside hadrons.
Asymptotic freedomRelated: Its scale dependence is calculable using QCD evolution equations.
AntiquarkRelated: Antiquark distribution functions quantify their momentum inside a hadron.
Up quarkRelated: It quantifies how the proton’s up quarks share its momentum.
PartonRelated: It quantifies the momentum fractions carried by the partons that collide.
