[streynj-nis] 
| 1. | the quality or condition of being strange. |
| 2. | Physics. a quantum number assigned the value −1 for one kind of quark, +1 for its antiquark, and 0 for all other quarks; the strangeness of a hadron is the sum of the values for the strangeness of its constituent quarks and antiquarks. Symbol: S |

| strangeness (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. |
