Strangelets at finite temperature
M. G. Mustafa, A. Ansari
Abstract
Within the MIT bag model picture of QCD, we have studied the stability of finite size strangelets at finite temperature with baryon number A ≤ 100. The light quarks u and d are considered massless while mass of the s quark is taken as 150 MeV. Using discrete eigen energies of the non-interacting quarks in the bag, grand canonical partition function is constructed and then the free energy is minimized with respect to the bag radius. In the T→ 0 limit clear shell structures are found which persist upto about T=10 MeV. Infact for A=6 the shell structure disappears only at T > 20 MeV.
