Search for Next-to-Minimal Supersymmetric Higgs Bosons in the h→aa→μμμμ, μμττ Channels Using pp-bar Collisions at s√=1.96 TeV

Abstract

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 4.2 fb(−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 M(a) and M(h).
