Explicit expressions for all diagrams are provided, which result in contributions to all relevant partial waves.17 p.application/pdfeng(c) American Physical Society, 2013Física nuclearReaccions nuclearsInteraccions febles (Física nuclear)Teoria quàntica de campsNuclear physicsNuclear reactionsWeak interactions (Nuclear physics)Quantum field theoryConstraints on the effective field theory for the Lambda N --> NN transitioninfo:eu-repo/semantics/article6324472017-02-22info:eu-repo/semantics/openAccess
