A search for pair production of doubly charged Higgs bosons in the process pp̅H++H-- → μ+μ+μ-μ- is performed with the D0 run II detector at the Fermilab Tevatron. The analysis is based on a sample of inclusive dimuon data collected at an energy of √s = 1.96 TeV, corresponding to an integrated luminosity of 113 pb-1. In the absence of a signal, 95% confidence level mass limits of M(HL±±) > 118.4 GeV/c2 and M(HR±±) > 98.2 GeV/c2 are set for left-handed and right-handed doubly charged Higgs bosons, respectively, assuming 100% branching into muon pairs.
