Thermal conductivity and shear viscosity of npe$mu$ matter in non-superfluid
neutron star cores are considered in the framework of Brueckner-Hartree-Fock
many-body theory. We extend our previous work (Shternin, Baldo and Haensel,
2013) by analysing different nucleon-nucleon potentials and different
three-body forces. We find that the use of different potentials leads up to one
order of magnitude variations in the values of the nucleon contribution to
transport coefficients. The nucleon contribution dominates the thermal
conductivity, but for all considered models the shear viscosity is dominated by
leptons.
