摘要：

The decay of massive neutrinos to final states containing only invisible particles is pearly constrained experimentally. In this letter we describe the constraints that can be put on neutrino mass and lifetime using CMBR measurements. We find that very tight lifetime limits on neutrinos in the mass range 10 eV - 100 keV can be derived using CMBR data from upcoming satellite measurements. (C) 1998 Elsevier Science B.V.
