TL;DR
This paper investigates the formation of stable quark nuggets during the early universe's QCD phase transition and explores their potential as dark matter candidates.
Contribution
It provides a calculation of quark nugget size distribution and assesses their viability as dark matter.
Findings
Large number of stable quark nuggets could form during the QCD phase transition.
Quark nuggets are viable candidates for cosmological dark matter.
The size distribution of quark nuggets is characterized in the study.
Abstract
We calculate the size distribution of quark nuggets, which could be formed due to first order QCD phase transition in the early universe. We find that there are a large number of stable Quark Nuggets which could be a viable candidate for cosmological dark matter.
