Abstract
The properties of strangelets at finite temperature are studied within the framework of a baryon densitydependent quark mass model, where a new quark mass scaling and self-consistent thermodynamic treatment are adopted. The effects of finite volume and Coulomb energy are taken into account. Our results show that the temperature , baryon number , and perturbation interactions have strong influences on the properties of strangelets. It is found that the energy per baryon and charge-to-mass ratio decrease with baryon number , while the mechanically stable radius and strangeness per baryon are increasing. For a strangelet with a fixed baryon number, we note that as temperature increases the quantities , , and are increasing while is decreasing. The effects of confinement and perturbative interactions are investigated as well by readjusting the corresponding parameters.
