Difficulties with interpretation of underground muons from Cygnus X3
Abstract
A possibility is analyzed to explain the underground muon flux detected from Cygnus X3, using new particles (cygnets). The following constraints on the cygnet properties are obtained: on the life time tau is greater than 1.3 ^{6} (gamma 10^{s}) where gamma is the cygnet Lorentz factor, on the mass, m is less than 5.7 (E/100 TeV) GeV where E is the cygnet energy, on the electric charge Q is less than 2.10 ^{7e} and on the mean scattering angle (due to an arbitrary process) on the way from Cygnus X3 to the sun theta is less than 4.10 ^{3} grad. It is shown that the NUSEX data (the angular spread of muons withing 10 ^{0} box of observation and the dependence of the Cygnus X3 exposition time on the depth of the matter along the observation line) contradict muon generation in the atmosphere and require muon generation in the ground. These data determine narrow boundaries for the cygnetnucleon interaction crosssection 2 b is less than sigma is less than 10 b. The cross section low limit for the cygnet production in reaction pp yields CX is obtained from a constraint on the flux of underground muons generated by neutrinos: sigma(pp yields CX) is greater than 10 E_{c}(1 TeV)^{1.1} b where E_{c} is the energy of cygnets responsible for the muon flux observed by NUSEX.
