摘要：

We discuss the prospects for improved upper limits on neutrino masses that may be provided by a core-collapse supernova explosion in our Galaxy, if it exhibits time variations in the neutrino emissions on the scale of a few milliseconds as suggested by recent two-dimensional simulations. Analyzing simulations of such neutrino emissions using the wavelet technique adopted in [J. Ellis, H.-T. Janka, N.E. Mavromatos, A.S. Sakharov, and E.K.G. Sarkisyan, Phys. Rev. D 85, 045032 (2012)], we find that an upper limit m(nu) similar to 0.14 eV could be established at the 95% confidence level if the time variations in emissions were to be preserved during neutrino propagation to the Earth.
