Review of Neutrino Mass Measurements

摘要

The current status of the experimental search for neutrino mass is reviewed, with emphasis on direct kinematic methods. New data on the /tau/ neutrino from the Argus collaboration have reduced the upper mass limit a factor of 2. The situation concerning the electron neutrino mass as measured in tritium beta decay is essentially unchanged from a year ago. Simpson and Hime report finding evidence for a 17-keV neutrino in the beta decay of sup 35 S. There may be evidence for neutrino mass and mixing in the SN1987a data. 62 refs., 4 figs.
