Magnetized strangelets at finite temperature

TL;DR

This paper investigates the stability and properties of magnetized strangelets at finite temperature, considering massive quarks and different phases, concluding that magnetic fields enhance their stability in astrophysical and collider environments.

Contribution

It introduces a detailed analysis of magnetized strangelets including temperature effects and massive quarks, highlighting their increased stability under magnetic fields and in superconducting phases.

Findings

Magnetic fields stabilize strangelets even at finite temperatures.

Magnetized color flavor locked phase strangelets are more stable than ordinary ones.

Temperature effects slightly reduce but do not negate magnetic stabilization.

Abstract

The main properties of magnetized strangelets, namely, their energy per baryon, radius and electric charge, are studied. Temperature effects are also taken into account in order to study their stability compared to the 56Fe isotope and non-magnetized strangelets using the liquid drop model. Massive quarks are considered with the aim to have a more realistic description for strangelets in the astrophysical context and the environment of heavy ion colliders, playing also an important role in the thermodynamical quantities of the quark gas. It is concluded that the presence of a magnetic field tends to stabilize more the strangelets, even when temperature effects are taken into account. Magnetized strangelets in a paired superconductor phase (magnetized color flavor locked phase) are also discussed. It is shown that they are more stable than ordinary magnetized strangelets for typical gap values of the order of O(100) MeV.
