Summary
Preliminary results are reported of a search in 207 pb/sup -1/ of MARK II PEP data at ..sqrt..s = 29 GeV for lepton pairs (L/sup -/,L/sup 0/) where the L/sup 0/ mass can be close to, but not exceed, the L/sup -/ mass. The numbers of e - ..mu.., and 3 or more charged hadrons versus isolated e or ..mu.., events are compared to Monte Carlo predictions for e/sup +/e/sup -/ ..-->.. tau/sup +/tau/sup -/, e/sup +/e/sup -/ ..-->.. q anti q, and two-virtual-photon processes. Possible residual signals for (L/sup -/,L/sup 0/) pairs are compared to Monte Carlo simulations and 2sigma confidence level limits on the L/sup -/ and L/sup 0/ masses are presented.
