The Standard Model

High-energy cosmic ray electrons interaction with Dark Matter particles is considered. In particular, a weakening of energy spectrum of cosmic electrons is predicted resulting from inelastic electron scattering on hyperpions in the hypercolor extension of the Standard Model. Corresponding cross-section and angular distributions of secondary neutrino are calculated and studied. The number of events with these neutrinos at IceTop is also estimated.
