Search for the Standard Model Higgs Boson in thepp¯→ZH→νν¯bb¯Channel

We report a search for the standard model (SM) Higgs boson based on data collected by the D0 experiment at the Fermilab Tevatron Collider, corresponding to an integrated luminosity of $260{\mathrm{pb}}^{-1}$. We study events with missing transverse energy and two acoplanar $b$ jets, which provide sensitivity to the $ZH$ production cross section in the $\nu \overline{\nu }b\overline{b}$ channel, and to $WH$ production when the lepton from the $W\to \ell \nu$ decay is undetected. The data are consistent with the SM background expectation, and we set 95% C.L. upper limits on $\sigma (p\overline{p}\to ZH/WH)\times B(H\to b\overline{b})$ from $3.4/8.3$ to $2.5/6.3\mathrm{pb}$, for Higgs-boson masses between 105 and 135 GeV.
