  In supersymmetric theories with R-parity breaking, trilinear couplings of two
leptons to scalar sleptons are possible. In electron-positron collisions such
interactions would manifest themselves through contact terms in Bhabha
scattering and in annihilation to mu or tau pair Interpreting the high x, high
Q2 DIS HERA events as charm squark production with squark masses of order 200
GeV, the formation of tau sneutrinos with a mass 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.
