Abstract: We have developed a formalism for microscopic Brueckner-type calculations of dense nuclear matter that includes all types of baryon-baryon interactions and allows us to treat any asymmetry in the fractions of the different species (n, p, Λ, Σ-, Σ0, Σ+, Ξ-, and Ξ0). We present results for the different single-particle potentials, focusing on situations that can be relevant in future microscopic studies of beta-stable neutron star matter with strangeness. We find that both the hyperon-nucleon and hyperon-hyperon interactions play a non-negligible role in determining the chemical potentials of the different species.
