Scientific paper

In a recent Letter we presented the first numerical treatment of the full set of Boltzmann equations for the evolution of an MeV Majorana τ neutrino in the early Universe. The conclusion was that mass limits from big bang nucleosynthesis were significantly weakened compared to previous investigations. An error in our numerical code unfortunately invalidates the results. We present here the correct results that lead to a strengthening of earlier mass limits based on the integrated Boltzmann equation.
