Color–flavor locked strangelets with confinement and perturbative interactions

Abstract

The properties of color–flavor locked (CFL) strangelets are investigated with the latest quark mass scaling that includes both linear confinement and leading-order perturbative interactions. With a self-consistent thermodynamics, we find that the perturbative interaction increases CFL strangelets’ radius and energy per baryon, while the one-gluon-exchange interaction has the opposite effects. With the increasing of the baryon number [Formula: see text], the energy per baryon decreases the electric charge per baryon and approaches to zero eventually. Specially at comparatively large [Formula: see text], the electric charge is nearly proportional to the two-third power of [Formula: see text] with the proportional coefficient to be about half of that in the conventional bag model.
