Flux of Scalar Neutrino Dark Matter

Abstract

Recently the exotic event observed at the Yunnan Cosmic Ray Station (YCRS) is reinterpreted as a neutral supersymmetric (SUSY) particle bombarding on proton to produce a charged SUSY particle which decays afterwards. The kinematics analysis determines the lower bounds of its mass and lifetime. Taking this bounds as inputs and following recent literatures to assume the scalar neutrino (sneutrino) as the main constituent of the cold SUSY dark matter, we calculate the flux of sneutrino at the earth detector in terms of the standard rate equation of cosmic matter.

Detection of Supersymmetric Dark Matter

“…[3] and Ref. [10], the related Feynman diagrams at the tree level are shown in the references. By all the information we obtain the SUSY dark matter density n(T) in the present universe.…”
