论文摘要
使用大规模的蒙特卡洛模拟研究了宇宙射线与星际气体相互作用中抗较高的可能性。为此，以前开发的能量依赖性的合并机制被扩展为估计光抗核心的产生（$ {}^3 \ overline {\ text {he}} $和$ {}^4 \ 4 \ overline {\ text {he}}} $）。还研究了合并参数的不确定性及其对预期反粒子通量的影响。发现模拟背景抗磁通量低于使用数值缩放技术通过简化模型预测的通量。
The possibility of antihelium production in interaction of cosmic rays with the interstellar gas is studied using large-scale Monte Carlo simulations. For this purpose, an energy-dependent coalescence mechanism developed previously is extended to estimate the production of light antinuclei (${}^3\overline{\text{He}}$ and ${}^4\overline{\text{He}}$). The uncertainty in the coalescence parameter and its effect on the expected antiparticle flux is also investigated. The simulated background antihelium fluxes are found to be lower than the fluxes predicted by simplified models using numerical scaling techniques.
