quark numberの例文

例文

1. Nowadays it might be more accurate to speak of the conservation of "'quark number " '.
2. According to the Standard Model, protons, a type of baryon, are stable because baryon number ( quark number ) is conserved ( under normal circumstances; see chiral anomaly for exception ).
3. However, the neutrinos escape, violating lepton number, so the phase space for quark matter in compact stars only has two dimensions, temperature ( " T " ) and quark number chemical potential ?.
4. For large quantities that exist for long periods of time ( the " thermodynamic limit " ), we must take into account the fact that the only conserved charges in the standard model are quark number ( equivalent to baryon number ), electric charge, the eight color charges, and lepton number.
