Abnormal threshold behaviors of photo-pion production off the proton in the GZK region

Abstract The cosmic-ray spectrum structures help to study the acceleration and propagation mechanism of ultra-high energy cosmic rays, and these structures were predicted to culminate in a cut-off, named the Greisen–Zatsepin–Kuzmin (GZK) cut-off, near $$5\times 10^{19}~\textrm{eV}$$ 5 × 10 19 eV as...
