Abstract

We present a search for Higgs bosons in multilepton final states in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ recorded with the D0 detector at the Fermilab Tevatron Collider, using the full Run II data set with integrated luminosities of up to $9.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. The multilepton states considered are $ee\ensuremath{\mu}$, $e\ensuremath{\mu}\ensuremath{\mu}$, $\ensuremath{\mu}{\ensuremath{\tau}}_{h}{\ensuremath{\tau}}_{h}$, and like-charge ${e}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\mu}}^{\ifmmode\pm\else\textpm\fi{}}$ pairs. These channels directly probe the HVV ($V=W$, $Z$) coupling of the Higgs boson in production and decay. The $\ensuremath{\mu}{\ensuremath{\tau}}_{h}{\ensuremath{\tau}}_{h}$ channel is also sensitive to $H\ensuremath{\rightarrow}{\ensuremath{\tau}}^{+}{\ensuremath{\tau}}^{\ensuremath{-}}$ decays. Upper limits at the 95% C.L on the rate of standard model Higgs boson production are derived in the mass range $100\ensuremath{\le}{M}_{H}\ensuremath{\le}200\text{ }\text{ }\mathrm{GeV}$. The expected and observed limits are a factor of 6.3 and 8.4 above the predicted standard model cross section at ${M}_{H}=125\text{ }\text{ }\mathrm{GeV}$. We also interpret the data in a fermiophobic Higgs boson model.
