| dc.description.abstract | The universe was radiation dominated at red shifts higher than Zeq = 3:9x104 h2. In the radiation dominated phase, the temperature will be greater Teq = 9:2 h2eV and will be increasing as (1 + Z). As we go to earlier than phases of the universe the radiation will produce particle-antiparticle pairs of di erent kinds. These elementary particles will be interacting with each other via di erent processes which will try to maintain statistical equilibrium between the particles. In order to study the early phases of the universe, one would like to understand how the material content of the universe changes as it expands | en_US |
