We present a search for Higgs bosons in multilepton final states in pp-bar collisions at s√=1.96 TeV recorded with the D0 detector at the Fermilab Tevatron Collider, using the full Run II data set with integrated luminosities of up to 9.7 fb(−1). The multilepton states considered are eeμ, eμμ, μτhτh, and like-charge e(±)μ(±) pairs. These channels directly probe the HVV (V=W, Z) coupling of the Higgs boson in production and decay. The μτ(h)τ(h) channel is also sensitive to H→τ(+)τ(−) decays. Upper limits at the 95% C.L on the rate of standard model Higgs boson production are derived in the mass range 100≤M(H)≤200 GeV. The expected and observed limits are a factor of 6.3 and 8.4 above the predicted standard model cross section at M(H)=125 GeV. We also interpret the data in a fermiophobic Higgs boson model.
