Description
We discuss the stability of strangelets by considering dynamical chiral symmetry breaking and confinement. We use a U(3)LxU(3)R symmetric Nambu-Jona-Lasinio (NJL) model for chiral symmetry breaking supplemented by a boundary condition for confinement. It is shown that strangelets (finite number of strange quarks) with baryon number A < or approx. 103 is the lowest quark droplets. For the observables, we obtain the masses and the charge-to-baryon number ratios of the strangelets. These quantities are compared with the observed data of the exotic particles
