利用高能粒子相互作用的蒙特卡罗模型计算了宇宙线与太阳物质相互作用产生的中微子流。在地球上（在太阳的立体角内）产生的通量高于宇宙射线与地球大气相互作用产生的相应通量。然而，由于绝对速率很小，它不能作为中微子望远镜的实际“标准烛光”，也限制了中微子振荡的研究。另一方面，它促进了基于太阳中中性伴子湮灭的中微子的暗物质搜索。
The flux of neutrinos originating from cosmic ray interactions with matter in the Sun has been calculated based on Monte Carlo models for high energy particle interactions. The resulting flux at the Earth (within the Sun's solid angle) is higher than the corresponding one from cosmic ray interactions with Earth's atmosphere. The smallness of the absolute rate, however, precludes it as a practical "standard candle" for neutrino telescopes and limits neutrino oscillation searches. On the other hand, it facilitates dark matter searches based on neutrinos from neutralino annihilation in the Sun.
