Description
In this talk, I discuss the generation of carbon as
a function of the parameters of QCD+QED. First, in the
framework of chiral effective field theory, the quark
mass dependence of the nuclear forces and the constraints
on possible quark mass variations from Big Bang Nucleosynthesis
are discussed. Second, using nuclear lattice simulations,
I investigate the fine-tuning of the fundamental parameters
of QED+QCD that is consistent with the bounds on carbon
production through the triple-alpha process in stars.
