Production and detection of high-energy neutrinos from Cygnus X-3

Cygnus X-3 is a potent source of high-energy γ rays, with energies up to ${10}^4$ TeV. In the context of a model where these γ rays are produced by the collision of a high-energy proton beam with matter we calculate the flux, spectrum, and ‘‘light curve’’ of the neutrinos produced. Neutrinos with energies of 3–100 TeV may be detectable in large, underground detectors by the muons they produce in the surrounding rock.
