Science definitions for strangeness

strangeness

[ strānjnĭs ]

The property of containing a strange quark or antiquark. Strangeness is expressed in terms of an integer quantum number, -1 for each strange quark and +1 for each strange antiquark. Hadrons that possess strangeness are called strange. The total strangeness of a quantum system is unchanged by decay processes involving the strong or electromagnetic forces; however, decay through the weak force can change the total strangeness of the system. See also baryon number isospin.
