Abstract

The

Δ Q = 0

Δ S = 1

component of the unitary spin current is used in interactions that are both weak and electromagnetic. The effective coupling constant is determined from the experimental decay rate

Σ^{+} \to p + γ

. With the aid of symmetry arguments, the rare decay rates of the modes

B \to B^{'} + γ

B \to B^{'} + e^{+} + e^{-}

, and

K \to π + e^{+} + e^{-}

are computed.
