strangeness

The quality or condition of being strange.

A quantum property of strange quarks and of hadrons that contain strange quarks that is conserved in electromagnetic and strong interactions, but may not be conserved in weak interactions that cause the decay of strange hadrons.

The quantum number represented by this property, equal to the difference between the number of strange antiquarks and the number of strange quarks.

The state or character of being strange, in any sense of that word.

The state or quality of being strange (in any sense of the adjective).

The state or quality of being strange, odd or weird.

The product or result of being strange.

one of the quantum numbers of subatomic particles that depends upon the relative number of strange quarks and anti-strange quarks

(physics) one of the six flavors of quark
