CR proton spectrum multiplied by E^2.75, with fit curves compared to measurements from AMS-02 (M. Aguilar et al. 2015), DAMPE (F. Alemanno et al. 2026), and LHAASO (Z. Cao et al. 2025c). The blue and red curves represent the contributions of the first (I) and second (II) CR components, respectively. Two alternative assumptions for the extrapolation of the second CR component toward low energies are shown: (a) a pure power-law extrapolation (curve II) and (b) a scenario with low-energy hardening of the second component (curve ﹩{\rm{II}}^{\prime} ﹩), as discussed in the text. The solid and dashed black curves show the total proton spectrum in the two-component CR framework for the (a) and (b) scenarios, respectively. The corresponding best-fit parameters are listed in Table 1. The inset highlights the spectral structure in the multi-TeV energy range.
