Resumen:
We calculate the dependence of the deuterium binding energy upon theHiggs vacuum expectation value (v), by using different effectivenucleon-nucleon potentials, and set constraints on the time variation ofthe Higgs vacuum expectation value from Big Bang Nucleosynthesis. Theanalysis is based on the calculation of the abundances of primordial D,{4}He and {7}Li. Results are consistent withvariations of v in the early universe, within6 sigma, if all available data on primordial abundances are consideredin the analysis.
