Quark–hadron phase transition in massive gravity

Abstract

We study the quark-hadron phase transition in the framework of massive gravity. We show that the modification of the FRW cosmological equations leads to the quark-hadron phase transition in the early massive Universe. Using numerical analysis, we consider that a phase transition based on the chiral symmetry breaking after the electroweak transition, occurred at approximately 10µ seconds after the Big Bang to convert a plasma of free quarks and gluons into hadrons.
