Solar neutrino measurements in Super-Kamiokande-IV

Abstract: We report a search for time variations of the solar 8 B neutrino flux using 5,804 live days of Super-Kamiokande data collected between May 31, 1996, and May 30, 2018. Super-Kamiokande measured the precise time of each solar neutrino interaction over 22 calendar years to search for solar neutrino flux modulations with unprecedented precision. Periodic modulations are searched for in a data set comprised of five-day interval solar neutrino flux measurements with a maximum likelihood method. We also applied the L… Show more

“…Indeed, the measurements of 8 B neutrinos of Super-Kamiokande [5] and SNO [3] are consistent with a constant suppression of the expected flux. Super-Kamiokande Collaboration [5] finds a hint for day-night effect but does not see evidence of a decrease with the energy of the survival probability (in solar neutrino jargon, "upturn" means commonly a negative and measurable value of the slope at 8 B energies).…”

“…However, in a recent paper of SuperKamiokande Collaboration one reads that [5], there is still no clear evidence that the solar neutrino flavor conversion is indeed due to neutrino oscillations and not caused by another mechanism.…”

“…There are other charged-current and neutral-current interactions with 16 O nuclei that are subdominant. There are two data samples used by SK for low-energy analysis: one tuned for the supernova relic neutrino (SRN) search (Bays et al 2012) and another for the solar neutrino analysis (Abe et al 2016b). These are independent selection methods and apply to different energy ranges for the GW170817 event search.…”

“…Neutrino oscillation parameters are mostly constrained by solar neutrino experiments [40][41][42][43][44][45], the SuperKamiokande atmospheric neutrino data [37], and accelerator data from MINOS [46], T2K [47], and the NuMI Off-Axis ν e Appearance Experiment (NOνA) [48]. These imply the existence of two hierarchical mass-squared differences ∆m 2 21 and ∆m 2 32 and three nonzero mixing angles θ 13 , θ 12 , θ 23 .…”
