Title: The life and death of the 17 keV neutrino

Abstract:

The story of the electron neutrino that has started with Pauli in 1930 continues to occupy human scientific endeavors and will do so for ever; it seems. At heart of this story are the issues of mass and mixing. Both continue to be ultra-hot topics today and for years to come both theoretically and experimentally.

This humble and simple talk will cover work done between the years 1985 and 1995 at both the university of Oklahoma and Sana’a university addressing a 17 keV massive neutrino that was first claimed in 1985 and was finally buried during the years leading to 1995. It will cover a series of papers published in Physics Letters B and Physical Review D as well as a number of conference proceedings.

The 17 keV neutrino has long been dead but issues related to new physics versus the null hypothesis remain alive particularly relevant to experimental systematic errors or theoretical corrections and thus lessons learned from its short life will be summarized.
