Some supersymmetric models predicted long lived charged sleptons. Following Albuquerque, Burdman and Chacko \citealbu, we consider an exact process where the \widetildeτ, the supersymmetry partner of τ lepton, are produced inside the earth by collisions of high energy neutrinos with nucleons. We detailedly investigate the possible signals of upgoing \widetildeτ by comparing with the background muons where atmospheric neutrino flux is taken into account. The realistic spectra shows that km-scale experiments could see as many as 69 events a year by using the Waxman-Bahcall limit on the extraterrestrial neutrino flux.
