论文摘要
我们分析了在PEV能量状态下的非弹性质子 - 普罗氏胶碰撞中产生的最终(稳定)产品的能量分布 - 伽马射线,中微子和电子。假设这些磁场在周围的磁场中迅速冷却,我们还计算了辅助电子的同步辐射的能能谱。我们表明,同步加速器辐射的能量分布比原代质子的能量分布要浅得多,因此我们建议在粒子加速器的最高能量(截止)发射区域的光谱分析中利用这种特征。对于母质子中的各种能量分布,我们提出了截止区域中次生谱的简单分析表现。这些结果可用于解释来自PEVATRON的高能辐射 - 宇宙射线工厂加速质子,以最大1 pev的能量。
We analyze the energy distributions of final (stable) products - gamma rays, neutrinos, and electrons - produced in inelastic proton-proton collisions in the PeV energy regime. We also calculate the energy spectrum of synchrotron radiation from secondary electrons, assuming that these are promptly cooled in the surrounding magnetic field. We show that the synchrotron radiation has an energy distribution much shallower than that of primary protons, and hence we suggest to take advantage of such a feature in the spectral analysis of the highest energy (cut-off) emission region from particle accelerators. For a broad range of energy distributions in the parent protons, we propose simple analytical presentations for the spectra of secondaries in the cut-off region. These results can be used in the interpretation of high-energy radiation from PeVatrons - cosmic-ray factories accelerating protons to energies up to 1 PeV.
