Stability of strangelets at finite temperature [PDF]

Physical Review C, 2003
Using the quark mass density- and temperature dependent model, we have studied the thermodynamical properties and the stability of strangelet at finite temperature. The temperature, charge and strangeness dependences on the stability of strangelet are investigated.
