abstract
The solar neutrino capture rate measured by the Russian-American Gallium Experiment (SAGE) on metallic gallium during the period January 1990 through December 1997 is 67.2 (+7.2-7.0) (+3.5-3.0) SNU, where the uncertainties are statistical and systematic, respectively. This represents only about half of the predicted Standard Solar Model rate of 129 SNU. All the experimental procedures, including extraction of germanium from gallium, counting of 71Ge, and data analysis are discussed in detail.

Ultra-high-energy tau neutrino detections at GRAND and POEMMA are projected to constrain Lorentz invariance violation parameters orders of magnitude more stringently than current lower-energy probes.
PandaX-4T Run 2 data yields solar pp neutrino flux of (8.5 ± 3.5)×10^{10} cm^{-2}s^{-1} at 2.2σ, first positive indication below 165 keV electronic recoil.
