 +=== Wednesday, June 11 ===
 +  * produced plots of BBN abundance as function of grav. constant
 +  * tried to calculate and fit the $p(n,​\gamma)d$ rate to use as input; partially succeeded
 +
 +=== Thursday, June 12 ===
 +  * 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.
