Search for doubly-charged Higgs Boson production in the decay H++ H-- → μ+μ+μ-μ- with the D0 detector at √s = 1.96-TeV
- Stony Brook Univ., NY (United States)
This work presents a search for the pair production of doubly-charged Higgs Bosons in the process p$$\bar{p}$$ → H++H-- → μ+μ+μ-μ- using inclusive dimuon events. These data correspond to an integrated luminosity of about 113 pb 1 and were recorded by the D0 experiment between August 2002 and June 2003. In the absence of a signal, 95% confidence level mass limits of M(H$$±±\atop{L}$$) > 118.6 GeV/c2 and M(HR±±) > 98.1 GeV/c2 are set for left-handed and right-handed doubly-charged Higgs boson, assuming 100% branching into muons and hypercharge |Y| = 2 and Yukawa coupling h μμ > 10-7. This is the first search for doubly-charged Higgs bosons at hadron colliders. It significantly extends the previous mass limit of 100.5 GeV/c2 for a left-handed doubly-charged Higgs boson measured in the muon final states by the OPAL collaboration.
