Abstract:
We present a search for the production of excited or exotic muons (mu*) via
the reaction pbar + p -> mu* + mu -> mu gamma + mu using 371/pb of data
collected with the Run II CDF detector. In this signature-based search, we look
for a resonance in the mu-gamma mass spectrum. The data are compared to
standard model and detector background expectations, and with predictions of
excited muon production. We use these comparisons to set limits on the mu* mass
and compositeness scale Lambda in the contact interaction and gauge-mediated
models.
