Because the strong force conserves strangeness, it can produce strange particles only in pairs, in which the net value of strangeness is zero. This phenomenon, the importance of which was recognized by both Nishijima and the American physicist Abraham Pais in 1952, is known as associated production.

The decays proceeding over a “long” time, as in the case of the neutron, are called weak. Even lifetimes of 10−13 seconds are still considered as “long” in elementary particle physics, and the decay is called weak. A particle with such a lifetime down to 10−11 sec leaves an observable trace
