Are There Top Quarks In Superdense Hybrid Stars?

TL;DR

This paper investigates the theoretical possibility that primordial top quarks could survive in superdense hybrid stars, analyzing their potential existence in dense quark-neutron star cores.

Contribution

It introduces a model for zero-temperature, non-interacting quark-lepton matter in hybrid stars to explore the survival of top quarks under extreme conditions.

Findings

Primordial top quarks could theoretically exist in dense stellar cores.

Hybrid quark-neutron stars may sustain top quarks due to high density.

The study provides a framework for understanding top quark stability in astrophysical environments.

Abstract

It is examined whether primordial top quarks from the Big Bang could survive under natural conditions till present days. Hybrid quark-neutron stars, with dense enough core to maintain the existence of top quarks, is discussed. In this paper only final states are investigated. Zero temperature quark-lepton matter is modelled as as a gas of non-interacting particles. Local charge neutrality has been assumed in order to avoid volume interactions which would not make thermodynamical treatment possible.
