HIGH-ENERGY NEUTRINO PRODUCTION BY COSMIC-RAY INTERACTIONS IN THE SUN

The flux of neutrinos originating from cosmic ray interactions with ma tter in the Sun has been calculated based on Monte Carlo models for hi gh energy particle interactions. The resulting flux at the Earth (with in the Sun's solid angle) is higher than the corresponding one from co smic ray interactions with Earth's atmosphere. The smallness of the ab solute rate, however, precludes it as a practical ''standard candle'' for neutrino telescopes and limits neutrino oscillation searches. On t he other hand, it facilitates dark matter searches based on neutrinos from neutralino annihilation in the Sun.
