Abstract [en]

We present a search for Higgs bosons in multilepton final states in p (p) over bar collisions at root 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 ee mu, e mu mu, mu tau(h)tau(h) , and like-charge e(+/-) mu(+/-) pairs. These channels directly probe the HVV (V = W, Z) coupling of the Higgs boson in production and decay. The mu tau(h)tau(h) channel is also sensitive to H -> tau(+)tau(-) 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.
