摘要

We describe a new mechanism for the production of ultra high-energy neutrinos based upon meson synchrotron emission. The acceleration of ultra-relativistic protons and nu- clei in the presence of strong magnetic fields (H ∼ 1015 G) in such environments as Magnetars, or GRB central engines could be a viable site for strong meson synchrotron emission. We show that charged scalar mesons like π± (along with π0's), vector mesons like ρ, and even heavier mesons like DS; J/ψ and γ, could be emitted with high in- Tensity (∼ 10 3 times the photon intensity) through strong couplings to ultra-relativistic nucleons. We estimate the flux of energetic neutrinos originating from the decay of ultra- high-energy neutrons produced in a SGR magnetar environment by proton synchrotron emission of p → π+ + n. We deduce the event rate in energetic neutrino detectors and show that a nearby strong SGR burst might be detectable. We also analyze the possibil- ity that the synchrotron emission of massive mesons like the γ might produce a burst of three avors of ultra high-energy cosmic neutrinos with Ev ≥ 1012 eV and evaluate the spectra of νe, ν μ and ντ from this process.
