英文摘要 | Spectra of cosmic rays (CRs), and particularly their features, contain a lot of important information about the astroparticle physics and the fundamental physics. Realizing that the 4 PeV knee of CR nuclei and the 1 TeV spectral cutoff of the electron share almost the same Lorentz factor, we propose that CRs experience a threshold interaction with a new light particle X abundant in the Galaxy. The interaction CR + X -> CR thorn X' can take place when the effective energy is sufficient to convert it into another heavier unknown particle X' (as a representative to all possible threshold inelastic interactions). Under this scenario, we can reproduce the spectral break for both the nuclei and the electron and predict a zigzag spectrum for them. Given that there are great uncertainties in experiments, our model accommodates a wide mass range of the X from the ultralow value to around 1 eV. |
