Abstract

A search for pair production of doubly charged Higgs bosons in the process pp̅ → H⁺⁺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(H_L^±±) > 118.4 GeV/c² and M(H_R^±±) > 98.2 GeV/c² are set for left-handed and right-handed doubly charged Higgs bosons, respectively, assuming 100% branching into muon pairs.
