Tevatron searches for excited and exotic leptons
The Tevatron experiments, D0 and CDF, have searched for excited electrons and excited and exotic muons in Run II. Using 1 fb{sup -1} of data, D0 has searched for excited electrons. No excess above the standard model background is observed. Choosing the scale for contact interactions to be {Lambda} = 1 TeV, excited electron masses below 756 GeV are excluded at the 95% C.L. CDF has searched for excited and exotic muons using 371 fb{sup -1} of data. Using gauge mediated models with {Lambda}/f = m{sub {mu}*}, exotic muons are excluded for masses below 221 GeV. For compositeness models with {Lambda} = m{sub {mu}*}, masses below 853 GeV are excluded. Using a similar size data set, D0 get similar limits.
