Search for heavy metastable particles decaying to jet pairs in pp collisions at sqrt{s} = 1.96 TeV

Abstract

A search is performed for heavy metastable particles that decay into jet pairs with a macroscopic lifetime (ctau ~ 1 cm) in ppbar collisions at sqrt{s} = 1.96 TeV using data from the CDF II detector at Fermilab corresponding to an integrated luminosity of 3.2 fb^-1. To estimate the standard model background a data-driven approach is used. Probability-density functions are constructed to model secondary vertices from known processes. No statistically significant excess is observed above the background. Limits on the production cross section in a hidden valley benchmark phenomenology are set for various Higgs boson masses as well as metastable particle masses and lifetimes.
