Abstract: (APS)

We have investigated, in a mean-field approximation, the properties of multi-lambda matter within a highly nonlinear σ-ω obtained from a derivative coupling between the scalar and fermion fields. The matter composition and saturation properties are calculated. We also discuss the spin-orbit properties of the effective Lagrangian.

Lambda: hypernucleus
hypernucleus: (n)Lambda
model: coupling
coupling: model
field theoretical model: nonlinear
mean field approximation
baryon: density
