Search for next-to-minimal supersymmetric higgs bosons in the h→aa→μμμμ, μμττ channels using pp̄ collisions at s=1.96TeV

We report on a first search for production of the lightest neutral CP-even Higgs boson (h) in the next-to-minimal supersymmetric standard model, where h decays to a pair of neutral pseudoscalar Higgs bosons (a), using 4.2fb-1 of data recorded with the D0 detector at Fermilab. The a bosons are required to either both decay to μ+μ- or one to μ+μ- and the other to τ+τ-. No significant signal is observed, and we set limits on its production as functions of Ma and Mh. © 2009 The American Physical Society.
