2. The following problems appear while dealing with the weak interaction involving two pairs of baryons. To illustrate the problem, we choose the following example: The universal weak interaction between baryons may contain the following two terms: .

Gav + 75)$2°) GovaCl + ¥5)#4):

—Z_bs-y1 + 76)b4) Borel + ¥5)$2"). (6)

V2 Although representing two different combinations of baryon pairs formally, they are completely equivalent to each other mathematically. Thus the following question arises: Should the contributions of both terms be included

in the calculation? In this paper, it is assumed that only the contribution of one of the terms of (6) should be counted.

There is another related question, which can be illustrated by the following example. One of the diagrams which lead to the process:

3s — JN + (7) is the following: N a . <— > m x N Fig. 1

The weak interaction represented by the vertex on the left hand side is:

@ Wieasnie + ¥5)%r) Pnvul + ¥3)bs-). (8) 2

There are two operators py in the expression (8), both of which can represent the external neutron line in Fig. 1. Hence, the following question arises:
