Observation of the anisotropy of 10 TeV primary cosmic ray nuclei flux with the Super-Kamiokande-I detector
The relative sidereal variation in the arrival direction of primary cosmic ray nuclei of median energy 10 TeV was measured using downward, through-going muons detected with the Super-Kamiokande-I detector. The projection of the anisotropy map onto the right ascension axis has a first harmonic amplitude of $(6.64\ifmmode\pm\else\textpm\fi{}0.98\text{ }\text{ }\mathrm{stat}\ifmmode\pm\else\textpm\fi{}0.55\text{ }\text{ …
