Abstract
This study analyzes an 11-year cosmic ray dataset of positrons and antiprotons for planetary dependencies related to gravitationally focused dark matter streams. By projecting event timestamps onto planetary heliocentric longitudes, structured flux modulations are found. The results resemble previously reported planetary relationships in solar and terrestrial observables. This supports the possibility that streaming dark matter particles are focused toward Earth by solar system bodies, including the Moon. The findings suggest further searches using other cosmic ray channels, including existing very high-energy gamma-ray data.
