Tevatron searches for excited and exotic leptons

PDF Version Also Available for Download.

Description

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 ... continued below

For compositeness models with {Lambda} = m{sub {mu}*}, masses below 853 GeV are excluded. Using a similar size data set, D0 get similar limits.
