+ | * produced data and plots for BBN abundance as function of $\Lambda_{QCD}$ and $\mu_n$ | ||

+ | * also looked at the individual effects of $\Lambda_{QCD}$ on the actual inputs to the BBN calculation (neutron-proton mass splitting, neutron life time, deuteron energy, $p(n,\gamma)d$ rate) and identified the life time effect as the main effect driving the change in the <sup>4</sup>He abundance. | ||
