We have estimated higher order quantum gravity corrections to de~Sitter spacetime. Our results suggest that, while the classical spacetime metric may be distorted by the graviton s…

New Upper Limits on the Tau Neutrino Mass from Primordial Helium Considerations
A. D. Dolgov, I. Z. Rothstein
In this paper we reconsider recently derived bounds on tau neutrinos, taking into account previously unaccounted for effects. We find that, assuming that the neutrino life-ti…
