Abstract:
We present the results of a search for doubly charged
Higgs bosons (H±±) decaying to dileptons (ll') using ~
240 pb-1 of pp-bar 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 sigma (pp-bar-->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 H±±L 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
H±±R in the µµ channel, all at the 95% confidence level.
