K. Nagano et al., EFFECT OF SOUND BRANCH OF PION ON NONMESONIC LAMBDA-DECAY IN NUCLEAR-MATTER, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 109(10), 1996, pp. 1471-1476
We have studied the effect of the sound branch of pion on the non-meso
nic decay width of the Lambda in nuclear matter. We find that its effe
ct is sensitive to the energy release and the correlation parameter g'
