Chiral symmetry, nonleptonic hyperon decay, and the Feinberg-Kabir-Weinberg theorem
Journal Article

· Phys. Rev. D; (United States)
We demonstrate that additional (kaon-pole) diagrams must be appended to the traditional commutator-plus-baryon-pole approach to nonleptonic hyperon decay. The modified analysis satisfied the constraints of the Feinberg-Kabir-Weinberg theorem. The new terms are not numerically significant in the case of the usual current-current Hamiltonian, in the continuum limit, but can be important for work using lattice techniques or for other Hamiltonians.
