Another general fact is that the strong nuclear force cannot change the flavor of a quark. The up quark or u quark (symbol: u) is the lightest of all quarks, a type of elementary particle, and a major 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 and a bare mass of 2.2 +0.5 The u-, d-, and s-quark massesareestimatesofso-called“current-quark masses,” in a mass-independent subtraction scheme such as MS at a scale µ ≈ 2 GeV. The c- and b-quark masses are the “running” masses in the MS scheme. This can be different from ms = 93 +11 − 5 MeV Charge = Figure 6.6.

2014-04-11 · Putting all of that aside, however, let’s focus on the quarks! The six quarks, in order of increasing heaviness, are listed below. up quark: mass 2.3 MeV, charge +2/3e; down quark: mass 4.8 MeV, charge -1/3e; strange quark: mass 95 MeV, charge -1/3e; charm quark: mass 1.275 GeV, charge +2/3e; bottom quark: mass 4.18 GeV, charge -1/3e

Since three spin − 1 / 2 − 1 / 2 quarks can combine to produce a particle with spin of either 1/2 or 3/2, the quark composition is consistent with the known spin ( s = 1 / 2 s = 1 / 2 ) of Ξ 0 Ξ 0 .

Because quark Cooper pairs harbor color charge, such a phase of quark matter would be color superconductive; that is, color charge would be able to pass through it with no resistance.
