Thanks for your reply Orodruin. What do I mean by physical real quantity? If I understand correctly, deep inelastic scattering experiments tell us protons are made of charged particles...but I am not sure DIS can tell protons are made of only uud quarks. Am I right?

Im carefully studying Deep Inelastic Scattering and I have the doubt if valence quarks are real physical entities or if they are just a way we can think hadrons are built. I understand that inside hadron we have the Parton Distribution Functions that say that there are an infinite number of...
