Prospects of a Search for Neutral, Long-Lived Particles using Photon Timing at CDF

Abstract

We present the prospects of searches for neutral, long-lived particles which decay to photons using their time of arrival measured with a newly installed EMTiming system at CDF. Using GMSB ${\tilde{\chi }}_1^0\to \gamma \tilde{G}$ models we estimate the expected 95% confidence level exclusion regions as a function of the neutralino mass and lifetime. We find that a combination of single photon and diphoton analyses should allow the Tevatron in run II to easily extend the exclusion regions from ALEPH at LEP II, and cover parts of the theoretically favored $m_{\tilde{G}}$ < few keV/c^2 GMSB parameter space.
