Short range correlations in the weak decay of Lambda hypernuclei

ABSTRACT The differences found in the relativistic and nonrelativistic methods used in the literature to account for short range nuclear correlations in the decay of Λ hypernuclei are analyzed. By means of a schematic microscopic model for the origin of correlations, the appropriate method to includ...
