Description
A search for exotic unstable neutral and charged heavy leptons as well as for stable charged heavy leptons is performed with the L3 detector at LEP. Sequential, vector and mirror natures of heavy leptons are considered. No evidence for their existence is found and lower limits on their masses are set.

A search for exotic unstable neutral and charged heavy leptons as well as for stable charged heavy leptons is performed with the L3 detector at LEP. Sequential, vector and mirror natures of heavy leptons are considered. No evidence for their existence is found and lower limits on their masses are set.Files
00004 The distribution of a) the sum, $E_{jet_1} + E_{jet_2}$, of the energies of the hadronic jets normalized to the beam energy, b) the normalized visible energy in the event, c) the acollinearity angle of the two W candidates, d) the total transverse momentum, $p_t$. The points are the data, the solid histogram is the background Monte Carlo. The shaded histogram represents the simulated signal for e$^+ $e$^- \rar \mathrm{L^+} \mathrm{L^-}$ for a sequential charged lepton mass equal to 95 \GeV. The normalization for the signal Monte Carlo is scaled by a factor of 2 for better visibility. The arrows indicate the values of the applied cuts after all the other selection requirements.
