Photon Creation in the Universe and Primordial Nucleosynthesis
Published online by Cambridge University Press: 25 May 2016
Abstract
In hot big bang cosmologies, the irreversible process of continous photon creation may phenomenologically be described through a thermodynamic approach. In these models, the radiation temperature law depends on a phenomenological parameter β which is closely related to the photon creation rate. It is shown that a stringent constraint on the value of this parameter is imposed from primordial nucleosynthesis.
