摘要: Abstract In the context of nucleon structure, Wigner distribution has been commonly used to visualize phase-space quarks and gluons inside nucleon. However, does not allow for a probabilistic interpretation because it takes negative values. pursuit positive in QCD, we introduce Husimi demonstrate its advantages via simple one-loop example. We also comment on possible connection semiclassical approach saturation physics at small-x.
