Primordial Nucleosynthesis with Massive Tau Neutrinos
J. B. Rehm, G. G. Raffelt, A. Weiss
A massive long-lived tau neutrino in the MeV regime modifies the primordial light-element abundances predicted by big-bang nucleosynthesis (BBN) calculations. This effect has been…

Red giant bound on the axion-electron coupling reexamined
G. Raffelt, A. Weiss
If axions or other low-mass pseudoscalars couple to electrons (``fine structure constant'' ) they are emitted from red giant stars by the Compton process and by b…

Standard and Non-Standard Plasma Neutrino Emission Revisited
M. Haft, G. Raffelt, A. Weiss
On the basis of Braaten and Segel's representation of the electromagnetic dispersion relations in a QED plasma we check the numerical accuracy of several published analytic approxi…
