It was postulated after the discovery of several heavy particles thought to be formed by strong nuclear reactions but did not interact with matter via that force.

It was postulated after the discovery of several heavy particles thought to be formed by strong nuclear reactions but did not interact with matter via that force. Having only integer values, it is always conserved in strong nuclear reactions that created the heavy particles but not in the weak interactions that cause their decay. Since it must be conserved, heavy particles can only be produced in pairs where the net value is zero, a process called associated production. FTP, identify this quantum property, first proposed by Nishijima and Gell-Mann.
