Da questa collisione vengono generati neutroni, protoni, pioni ($\pi^0$, $\pi^+$, $\pi^-$), antinuetroni, antiprotoni, kaoni e iperoni. I $\pi^0$ decadono elettromagneticamente in due $\gamma$ (fotoni) e questi ultimi possono materializzarsi in coppie $e^+ \, e^-$ (positroni, elettroni). I pioni carichi possono interagire con altri nuclei presenti nell'atmosfera o decadere in leptoni $\mu$ (muoni) e neutrini $\nu$. Gli elettroni irradiano energia sotto forma di raggi $\gamma$ (radiazione di frenamento). Le linee tratteggiate indicano che altre reazioni possono avvenire.};
