Abstract

Charged pions produced in very high energy hadronic interactions might be the dominant source of cosmic neutrinos in the GeV-TeV range. The spectral energy power of π+ radiation by high-energy protons moving in strong magnetic fields typical for magnetars is determined with a semiclassical treatment of the effective pion-nucleon model. The main characteristics emerging from a saddle-point approximation to the summation over the allowed range of Landau levels is a sharp lower cut: Eπ ≥ 0.25Ep. The magnitude of the spectral power agrees in this region with the synchrotron radiation spectra of neutral pions.
