Search for High Mass Resonances in CDF Di-Muon Data

Chris Hays (Oxford University)

Neutral resonances have a long and illustrious history, and could well provide the next big discovery in particle physics. I present a new search for high-mass neutral resonances in the CDF dimuon data, the most sensitive such search to date. The analysis applies the novel technique of probing the inverse mass spectrum, for which the detector resolution is constant in the search region. The results are interpreted in terms of spin 0, 1, and 2 resonances, using sneutrino, Z', and graviton models, respectively.
