The Fermi hypernetted chain technique (FHNC) has been extended to the problem of calculating the Λ-binding to nuclear matter. By using graphical techniques and considering the Λ-particle as an impurity, cluster expansions for ΛN and NN distribution functions have been obtained in terms of irreducible graphs. Topological analyses of the graphs have been made to obtain hypernetted chain equations for the two distribution functions for state-independent ΛN and NN correlation factors. Calculations are carried out for the Λ-binding energy including the rearrangement energy terms by employing central, state-independent and spin-averaged hard-core ΛN potentials. Results are in direct contradiction to the reaction matrix results as well as the empirical estimates. © 1980.
