Strangelets at finite temperature.

چکیده
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.

متن کاملStability of strangelet at finite temperature
Using the quark mass densityand 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. We find that the stable strangelets are only occured in the high strangeness and high negative charge region. PACS number: 12.39.Ki, ...
متن کاملColour-singlet Strangelets at Finite Temperature
Considering massless u and d quarks, and massive (150 MeV) s quarks in a bag with the bag pressure constant B1/4 = 145 MeV, a colour-singlet grand canonical partition function is constructed for temperatures T = 1−30 MeV. Then the stability of finite size strangelets is studied minimizing the free energy as a function of the radius of the bag. The colour-singlet restriction has several profound...
متن کاملCharge, strangeness and radius of strangelets
We investigate, at both zero and finite temperature, the properties of strangelets versus the electric charge Z and strangeness S. The strangelet radius is not a monotonic function of either charge or strangeness, and a minimum is reached in the (Z, S) plane. However, the thermodynamically stable strangelets do not correspond to the radius minimum. The minimum radius always appears at positive ...
متن کاملColor-flavor locked strangelets.
Finite lumps of color-flavor locked strange-quark matter (CFL strangelets) are significantly more stable than strangelets without color-flavor locking for wide ranges of parameters, increasing the likelihood of strangelet metastability, or even absolute stability beyond some minimum baryon number A(min). Whereas bulk CFL strange-quark matter is electrically neutral, CFL strangelets are positive...
