Feasibility of searches for a Higgs boson using $H\to W^{+}{W}^{-}\to l^{+}{l}^{-}$ + missing $p_T$ and high $p_T$ jets at the Fermilab Tevatron

The sensitivity of standard model Higgs boson searches at the Tevatron experiments with a mass $135<M_H<190\mathrm{GeV}/c^2$ using the channel $H\to W^{+}{W}^{-}\to l^{+}{l}^{-}{\mathrm{p̸}}_T(l=e,\mu )$ is discussed. Three new event selections involving Higgs in association with one or two high $P_T$ hadronic jets are discussed. Using leading order matrix elements and a conservative cut-based analysis a 95% confidence level exclusion on $\sigma \times \mathcal{B}(H\to W^{+}{W}^{-})$, 1.6 times larger than that predicted by the standard model for $M_H=165\mathrm{GeV}/c^2$, may be achieved with $5{\mathrm{fb}}^{-1}$ of integrated luminosity. By combining these three event selections with the existing analysis, the sensitivity of CDF and D0 could improve significantly.
