Does anyone know where I can learn more about the relation between the reaction rate ( $\Gamma$ ) of the primordial elements and the Hubble parameter ( $H$ ) at the early universe? Principaly at the transition from the radiation dominated era to the the matter dominated era?

A great reference for the early universe is the book by Kolb & Turner: The Early Universe
