概要
- 論文の詳細を見る
Lightlike chiral algebra is applied to the investigation of the nonleptonic hyperon decays. We use the light-front reduction formula to the decay amplitudes and take the limit q_π^+ and q_π^<bottm>→0. We do not have to make q_π^- tend to zero, in contrast to the conventional current algebraic approach. We present dynamical conditions under which the ΔI=1/2 rule and the Lee-Sugawara relation are obtained. They are represented in terms of the relations among various reduced matrix elements of the Hamiltonian.
