Examples

All quarks carry an additive, conserved quantum number called a baryon number (B), which is + 1 3 for quarks and − 1 3 for antiquarks. Source: Internet

The baryon number (B) is + 1 3 for all quarks, as baryons are made of three quarks. Source: Internet

The excess of baryons over antibaryons in the present universe is thought to be due to non- conservation of baryon number in the very early universe, though this is not well understood. Source: Internet

The universe, as a whole, seems to have a nonzero positive baryon number density — that is, matter exists. Source: Internet
