Primordial Nucleosynthesis and Finite Temperature QED    [PDF]

Mahnaz Q. Haseeb, Omair Sarfaraz
Abundances of light nuclei formed during primordial nucleosynthesis are theoretically well predicted by Standard Big Bang Model. These predictions have been compared with the latest data from WMAP with precisions higher than ever before. Therefore, an even more sharpened refinement in theoretical estimates is required through all possible approaches. We evaluate corrections to the change in helium abundance parameter during primordial nucleosynthesis using finite temperature corrections up to two loop level, for the first time. The values estimated are in measurable ranges of present and future observational probes.
