Abstract

We have measured the weak decay asymmetry parameters (α ) for two Λ decay modes. Our measurements are α = -0.94 for the decay mode Λ → Λπ and α = -0.45 ±0.31 ±0.06 for the decay mode Λ → Σ π . By combining these measurements with the previously measured decay rates, we have extracted the parity-violating and parity-conserving amplitudes. These amplitudes are used to test models of nonleptonic charmed baryon decay. © 1995. Λ c c Λ c -0.06-0.06 c Λ c c + +0.21+0.12 + + + 0
