Scientific paper

Results are presented on searches of doubly charged Higgs bosons (H±±) using data collected by CDF and DØ experiments at the Fermilab Tevatron Collider at a center of mass energy of 1.96 TeV. CDF searched for the decay H±± → l±l± in ee, eμ, μμ channels with 240 pbˑ integrated luminosity. Since no signal is seen, lower limits on HL±± (left-handed) mass of 133 GeV/c2 (ee), 115 GeV/c2 (eμ), and 136 GeV/c2 (μμ) and on HR±± (right-handed) mass of 113 GeV/c2 (μμ) have been placed at 95% confidence level (C.L.). DØ searched for H±± in the μμ decay channel with 113 pb-1 integrated luminosity. In the absence of a signal, mass limits of M(HL±±) > 118.4 GeV/c2 and M(HR±±) > 98.2 GeV/c2 at 95% C.L. are obtained. CDF has also searched for long lived H±± using 206 pb-1 integrated luminosity and set a lower limit of 134 GeV/c2 on its mass.
