Abstract
We search for excited and exotic muon states μ* using an integrated luminosity of 371  pb-1 of pp&#773; collision data at √s=1.96  TeV. We search for associated production of μμ* followed by the decay μ*→μγ. We compare the data to model predictions as a function of the mass of the excited muon Mμ*, the compositeness energy scale Λ, and the gauge coupling factor f. No signal above the standard model expectation is observed. We exclude 107<Mμ*<853  GeV/c2 for Λ=Mμ* in the contact interaction model, and 100<Mμ*<410  GeV/c2 for f/Λ=10-2  GeV-1 in the gauge-mediated model, both at the 95% confidence level.
