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 (B − L) 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)
“It little profits that an idle king,
By this still hearth, among these barren crags,
Matched with an aged wife, I mete and dole
Unequal laws unto a savage race
That hoard, and sleep, and feed,”
—Alfred Tennyson (1809–1892)
