Abstract:

Following a previous paper, we propose selection rules for weak processes. The first rule is Δnt = 0, where Δnt = n + \overlinen; n(\overlinen) indicates an (anti-)urbaryon number. The second rule is that a dimensionality of the SU(3) representation of hadronic system is conserved along s- or t-channel dependig on the parity property. These rules are applied to decay processes of new hadrons, and indication of which has been observed in a cosmic ray jet. We further attempt some conjectures on the second event that has recently been reported.
