Article Synopsis
- The study analyzed 5804 days of Super-Kamiokande data from 1996 to 2018 to detect variations in solar ^{8}B neutrino flux.
- The researchers utilized a five-day interval measurement approach and employed maximum likelihood and Lomb-Scargle methods to find any periodic modulations.
- They found a significant modulation related to Earth's elliptical orbit around the Sun, with measurements of eccentricity and perihelion shift aligning with astronomical data.

Article Synopsis
- - The T2K experiment reports enhanced measurements of neutrino oscillation parameters through new proton-on-target (POT) neutrino data, significantly improving analysis methods with a major focus on the near detector's new selection procedures.
- - This analysis is the first to utilize data from the NA61/SHINE experiment, helping to refine the neutrino flux model and enhance the neutrino interaction model by incorporating new nuclear effects.
- - Both frequentist and Bayesian approaches indicate a preference for normal mass ordering and a nearly maximal CP-violating phase, with notable exclusions and constraints on certain parameters aligning with past T2K studies.
We report a search for cosmic-ray boosted dark matter with protons using the 0.37 megaton×years data collected at Super-Kamiokande experiment during the 1996-2018 period (SKI-IV phase). We searched for an excess of proton recoils above the atmospheric neutrino background from the vicinity of the Galactic Center.
