|1.||the state or quality of being strange|
|2.||physics a property of certain elementary particles, characterized by a quantum number (strangeness number) conserved in strong and electromagnetic but not in weak interactions. It is associated with the presence of strange quarks|
strangeness [%PREMIUM_LINK%] (strānj'nĭs) Pronunciation Key |
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.
