We present a search for long-lived doubly charged Higgs bosons (H(++/--)), with signatures of high ionization energy loss and muonlike penetration. We use 292 pb(-1) of data collected in p (p) over bar collisions at root s=1.96 TeV by the CDF II detector at the Fermilab Tevatron. Observing no evidence of long-lived doubly charged particle production, we exclude H(L)(++/--) and H(R)(++/--) bosons with masses below 133 GeV/c(2) and 109 GeV/c(2), respectively. In the degenerate case we exclude H(++/--) mass below 146 GeV/c(2). All limits are quoted at the 95% confidence level.

Abstract

We present a search for long-lived doubly charged Higgs bosons (H(++/--)), with signatures of high ionization energy loss and muonlike penetration. We use 292 pb(-1) of data collected in p (p) over bar collisions at root s=1.96 TeV by the CDF II detector at the Fermilab Tevatron. Observing no evidence of long-lived doubly charged particle production, we exclude H(L)(++/--) and H(R)(++/--) bosons with masses below 133 GeV/c(2) and 109 GeV/c(2), respectively. In the degenerate case we exclude H(++/--) mass below 146 GeV/c(2). All limits are quoted at the 95% confidence level.
