Chiral symmetry breaking and stability of strangelets

Abstract

We discuss the stability of strangelets by considering dynamical chiral symmetry breaking and confinement. We use a $U(3{)}_L\times U(3{)}_R$ symmetric Nambu--Jona-Lasinio model for chiral symmetry breaking supplemented by a boundary condition for confinement. It is shown that strangelets with baryon number $A<2\times 10^3$ can stably exist. 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.
