Abstract
In supersymmetric theories with R-parity breaking, trilinear couplings of leptons to scalar sleptons, including sneutrinos, are possible. In electron-positron collisions such interactions would manifest themselves through contact terms in Bhabha scattering and annihilation to mu or tau pairs. Interpreting the high x, high Q^2 DIS HERA events as either charm or top squark production with squark masses of order 200 GeV, the formation of mu and tau sneutrinos with masses in the range close to the LEP2 energy or even in reach is an exciting speculation which can be investigated in the coming LEP2 runs with energies close to 200 GeV.
