Abstract
The properties of strangelets at zero temperature with a new quark model that includes both the confinement and one-gluon-exchange interactions is studied in a fully self-consistent method. The charge and parameter dependence of the stability of strangelets are discussed. It is found that the one-gluon-exchange interaction lowers the energy of a strangelet, and consequently allows the strangelet to be absolutely stable. The stable strangelet radius in the present model is smaller in comparison with the absence of one-gluon-exchange interaction, and can thus be much less than that of a normal nucleus with the same baryon number, according to the strength of the confinement and one-gluon-exchange interactions.
