Search for heavy metastable particles decaying to jet pairs in p(p)over-bar collisions at root s=1.96 TeV

A search is performed for heavy metastable particles that decay into jet pairs with a macroscopic lifetime (cτ∼1cm) in pp̄ collisions at √s=1.96TeV using data from the CDF II detector at Fermilab corresponding to an integrated luminosity of 3.2fb-1. To estimate the standard model background, a data-...

description A search is performed for heavy metastable particles that decay into jet pairs with a macroscopic lifetime (cτ∼1cm) in pp̄ collisions at √s=1.96TeV using data from the CDF II detector at Fermilab corresponding to an integrated luminosity of 3.2fb-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. © 2012 American Physical Society.
