Low energy neutrino physics at the Kuo-Sheng Reactor Laboratory in Taiwan

Abstract

Abstract. The TEXONO Collaboration has been pursuing a research program on low energy neutrino physics at the Kuo Sheng Reactor Neutrino Laboratory in Taiwan. We focus on the final results of our studies on neutrino magnetic moments and radiative decay lifetimes with a high-purity germanium detector. Limits of µν (νe) < 7.4 × 10 −11 µB at 90% confidence level were derived at a physics threshold of 12 keV and a background level of 1 keV −1 kg −1 day −1 , comparable to underground dark matter experiments. The other programs at Kuo-Sheng are described.
