Quark-hadron phase transition in massive gravity

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 $10 \mu$ seconds after the Big Bang to convert a plasma of free quarks and gluons into hadrons.
