Production of neutrinos and secondary electrons in cosmic sources

摘要: Abstract We study the individual contribution to secondary lepton production in hadronic interactions of cosmic rays (CRs) including resonances and heavier secondaries. For this purpose we use same methodology discussed earlier [C.-Y. Huang, S.-E. Park, M. Pohl, C.D. Daniels, Astropart. Phys. 27 (2007) 429], namely Monte-Carlo particle collision code DPMJET3.04 determine multiplicity spectra various particles with leptons as final decay states, that result from inelastic collisions cosmic-ray protons Helium nuclei interstellar medium standard composition. By combining simulation results parametric models for (with included) incident energies below a few GeV, where DPMJET appears unreliable, thus derive matrices all stable up about 10 PeV. apply calculate radio synchrotron radiation electrons young shell-type SNR, RX J1713.7-3946, which is measure age, spectral index rays, most importantly magnetic field strength. find multi-mG fields recently invoked explain X-ray flux variations are unlikely extend over large fraction radio-emitting region, otherwise spectrum energy window 0.1–100 GeV must be unusually hard. also muon event rate an IceCube-like detector induced by neutrinos high-energy γ-ray sources such Vela Jr. MGRO J2019+37. At TeV, or other word, 10 TeV neutrino energy, accumulation data 5–10 years would allow testing origin TeV γ-rays.
