Constituent quark
Additional recommended knowledgeIn the low energy limit of the QCD, a disturbance-theoretical description is not possible. Here, no Asymptotic freedom exists, but the interactions between valence quarks and sea-quarks gain strongly on significance. A part of the effects of the lake from virtual quarks and virtual gluons can be assigned in each case to a quark, so well that this is the one of the main proofs that the usage of the term constituent quark is just making sense. Accordingly to the Feynmangraphs, constituent quarks seem to be 'tightened' current quarks, thus, current quarks with constituent quark covering. These coverings are in the long run responsible for the large masses of the constituent quarks. Definition: Constituent quarks are valence quarks. In those, the correlations for the description of the hadrons guided by gluons and sea-quarks is to be put into effective quark masses of these valence quarks. The effective quark mass is called also constituent quark mass. Hadrons consist of 'sticking' constituent quarks. The use of the local term for the description of the hadrons used on light constituent quarks is not completely unproblematic.
