Time variation of the fine structure constant and of the Higgs vacuum expectation value on cosmological time scales

Aims. We study the time variation of both the fine structure constant, α, and the Higgs vacuum expectation value, v, during Big Bang nucleosynthesis (BBN). Methods. We calculate the primordial abundances of D, 4He, and 7Li by modifying Kawano's code, and by using observational data we set const...
