Strange Leptons

The consequences of the following two assumptions are discussed: (1) There exist strange leptons; (2) strangeness is conserved in all semileptonic interactions. These hypotheses could explain the absence of neutral currents in semileptonic processes and the $\Delta S=\Delta Q$ rule without assuming that the weak current transforms like a SU(3) octet. We propose experiments, well within the reach of present possibilities, to test these assumptions.
