Abstract

We search for excited and exotic muon states μ* using an integrated luminosity of 371pb1 of pp¯ collision data at s=1.96TeV. 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*<853GeV/c2 for Λ=Mμ* in the contact interaction model, and 100<Mμ*<410GeV/c2 for f/Λ=102GeV1 in the gauge-mediated model, both at the 95% confidence level.
