Abstract: We consider the ΛN → NN weak transition, responsible for a large fraction of the nonmesonic weak decay of hypernuclei.We follow the previously derived effective field theory and compute the next-to-leading one-loop corrections. Explicit expressions for all diagrams are provided, which result in contributions to all relevant partial waves.
