A possible interrelation between ordinary current×current
(J+J-type) picture and phenomenological two-body weak interaction
in nonleptonic weak decays is investigated. The investigation is based
U-1∂αLα(x)U = ∂αLα(x) +
where Lα(Lα) means an operator in the interaction
(Heisenberg) representation and U the unitary operator connecting
these two representations. The strong interaction is assued to be
given as products of appropriate
(V, A) currents. In the fundamental triplet model the two-body weak
interaction can be internally connected with the ordinary J+J-type
weak interaction. This interrelation requires both symmetric and
symmetry-breaking interactions (which are assumed to be of octet
current × octet current-type) of the form
GVV ·V + GAA ·A with GV = GA, where V(A) denotes
a vector (axial-vector) current.
At the hadron level, similar discussions are developed and we can
obtain a parallelism between triplet and hadron cases as far as we are
concerned with the weak interaction with |ΔI| = 1/2. It is to be
noted that as for the |ΔI| = 3/2 part we can find no connection
between two-body weak interaction and J+J-type interaction so that
we can say that the weak interaction with |ΔI| = 3/2 has a
structure essentially different from the one with |ΔI| = 1/2.
