Abstract
We present the results of a search for doubly charged Higgs bosons (H±±) decaying to dileptons (ll′) using ≈240 pb-1 of pp̅ collision data collected by the CDF II experiment at the Fermilab Tevatron. In our search region, given by same-sign ll′ mass mll′>80 GeV/c2 (100 GeV/c2 for ee channel), we observe no evidence for H±± production. We set limits on σ(pp̅ →H++H--→l+l′+l-l′-) as a function of the mass of the H±± and the chirality of its couplings. Assuming exclusive same-sign dilepton decays, we derive lower mass limits on HL±± of 133, 136, and 115 GeV/c2 in the ee, μμ, and eμ channels, respectively, and a lower mass limit of 113 GeV/c2 on HR±± in the μμ channel, all at the 95% confidence level.
