Book excerpt: The authors search for pair production of doubly charged Higgs particles (H{sup ±±}) followed by decays into electron-tau (e[tau]) and muon-tau ([mu][tau]) pairs using a data set corresponding to an integrated luminosity of 350 pb−1 collected from {bar p}p collisions at √s = 1.96 TeV by the CDF II experiment. They search separately for cases where three or four final-state leptons are detected, and then combine the results into limits for each exclusive flavor decay mode of the H{sup ±±}. Assuming 100% branching ratios of the H{sup {+-}{+-}} to left-handed e[tau] ([mu][tau]) pairs, they set an H{sup {+-}{+-}} lower mass limit of 114 (112) GeV/c2 at the 95% confidence level (C.L.).
