We systematically study two-body nonleptonic decays of light lambda hyperon Λ→pπ−(nπ0) with account for both short- and long-distance effects. The short-distance effects are induced by five topologies of external and internal weak W± exchange, while long-distance effects are saturated by an inclusion of the so-called pole diagrams with intermediate 12+ and 12− baryon resonances. The contributions from 12+ resonances are calculated straightforwardly by account for nucleon and Σ baryons whereas the contributions from 12− resonances are calculated by using the well-known soft-pion theorem in the current-algebra approach. It allows one to express the parity-violating S-wave amplitude in terms of parity-conserving matrix elements. From our previ...
