However, the antisigma baryon is made of two up antiquarks and one strange antiquark For example the sigma baryon (Σ +) is made of two up quarks and a strange quark.⇒ Each baryon has a corresponding antibaryon, which is constructed of the corresponding antiquarks ⇒ Other baryons (especially containing heavier quarks) have only really been observed at high-energies (e.g. ⇒ There are six quarks and baryons are made up of a combination of three of them, so there are many different possible baryons (e.g. ⇒ For example, see how the lepton number is preserved in β - decay, below: the total number of leptons before an interaction must be equal to the total number of leptons after an interaction ⇒ In any particle interaction the law of conservation of lepton number must be preserved i.e. All other non-leptonic particles have a lepton number of L = 0.All the antileptons (such as the positron) have a lepton number of L = -1, but a charge Q = +1(e) or 0. ![]()
