Abstract

We report the results of a search for pair production of doubly charged Higgs bosons via pp → H⁺⁺H^--X → μ⁺μ⁺μ^-μ^-X at √s = 1.96 TeV.We use a data set corresponding to an integrated luminosity of 1.1 fb^-1 collected from 2002 to 2006 by the D0 detector at the Fermilab Tevatron Collider. In the absence of an excess above the standard model background, lower mass limits of M(H^±±_L) > 150 GeV/c² and M(H^±±_R) > 127 GeV/c² at 95% C.L. are set, respectively, for left-handed and right-handed doubly charged Higgs bosons assuming a 100% branching ratio into muons.
