Scientific paper

We investigate the stability of strangelets in a chiral effective model. We focus on the effects of the chiral symmetry breaking in the strangelets by using the NJL model as an effective theory of QCD. The self-bound quark droplets are formulated by implementing the confinement picture in the MIT bag model. It is shown that the strangelets are not absolutely stable due to the chiral symmetry breaking and the large current mass as compared with light flavor. The observable quantities (the charge-mass ratios, the radii) of the strangelets are discussed to compare them with observed data in heavy ion collisions and/or in cosmic rays.
