TL;DR
This paper explores the properties of the early universe during the quark-hadron transition, analyzing hadron abundances and their evolution through kinetic theory to understand conditions from the quark-gluon plasma to neutrino decoupling.
Contribution
It provides a detailed kinetic theory analysis of hadronization and the evolution of hadron yields during the early universe's phase transition.
Findings
Hadron abundances remain stable after the quark-hadron phase transition.
The evolution of hadron yields is characterized in detail.
Hadronization process impacts subsequent particle abundances.
Abstract
The properties of the quark and hadron Universe are explored. Kinetic theory considerations are presented proving that hadron abundances after phase transformation from quarks to hadrons remain intact till abundances of hadrons become irrelevant. The hadronization process and the evolution of hadron yields is described in detail.
