摘要: Leading three-baryon forces are derived within SU(3) chiral effective field theory. Three classes of irreducible diagrams contribute: contact terms, one-meson exchange, and two-meson exchange diagrams. We provide the minimal nonrelativistic terms Lagrangian that contribute to these relations given for strangeness $S=0$ $\ensuremath{-}1$ sectors. In strangeness-zero sector we recover well-known three-nucleon from Explicit expressions $\mathrm{\ensuremath{\Lambda}}NN$ potential in isospin space presented.
