    "abstract": "The contribution of Lambda hyperons to neutrino scattering rates is\ncalculated in the random phase approximation in a model where the interaction\nis described by a Skyrme potential. Finite temperature and neutrino trapping\nare taken into account in view of applications to the deleptonization stage of\nprotoneutron star cooling. The hyperons can remove the problem of ferromagnetic\ninstability common to (nearly) all Skyrme parametrizations of the\nnucleon-nucleon interaction. As a consequence, there is not any longer a pole\nat the transition in the neutrino-baryon cross section. However there still\nremains an enhancement in this region. In the absence of ferromagnetism the\nmean free path in npLambda matter is reduced compared to its value in np matter\nas consequence of the presence of this additional degree of freedom. At high\ndensity the results are very sensitive to the choice of the Lambda-Lambda\ninteraction.",
