Flavour (particle Physics) - Conservation Laws

Conservation Laws

Absolutely conserved flavour quantum numbers are

  • electric charge (Q)
  • weak isospin (I3)
  • baryon number (B)
  • lepton number (L)

In some theories, the individual baryon and lepton number conservation can be violated, if the difference between them (BL) is conserved (see chiral anomaly). All other flavour quantum numbers are violated by the electroweak interactions. Strong interactions conserve all flavours.

Famous quotes containing the words conservation and/or laws:

    A country grows in history not only because of the heroism of its troops on the field of battle, it grows also when it turns to justice and to right for the conservation of its interests.
    Aristide Briand (1862–1932)

    Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same and everywhere one and the same in her efficiency and power of action; that is, nature’s laws and ordinances whereby all things come to pass and change from one form to another, are everywhere and always; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through nature’s universal laws and rules.
    Baruch (Benedict)
