New upper limit on neutrino magnetic moment

Reactor-based elastic scattering data analyzed

Enhanced constraints on neutrino electromagnetic properties

Abstract

The MUNU experiment uses the electron antineutrino-electron elastic scattering to examine the magnetic properties of the electron antineutrino. The detector is situated at 18 m from the reactor, serving as an electron antineutrino source. Data corresponding to 66.6 days reactor-on and 16.7 days reactor-off are reported in this study .The electron recoil spectrum is obtained, using the visual scanning procedure. A new limit on the neutrino magnetic moment is derived.
