WebThe up quark or u quark (symbol: u) is the lightest of all quarks, a type of elementary particle, and a significant constituent of matter.It, along with the down quark, forms the neutrons (one up quark, two down quarks) and protons (two up quarks, one down quark) of atomic nuclei.It is part of the first generation of matter, has an electric charge of + 2 / 3 e … WebWe compare the orbital angular momentum of the ‘quark’ in the scalar diquark model as well as that of the electron in QED (to order α) obtained from the Jaffe–Manohar decomposition to that obtained from the Ji relation. We estimate the importance of the vector potential in the definition of orbital angular momentum.
