“…The acquired data correspond to an integrated luminosity of approximately 7.5 fb −1 . Searches for the standard model Higgs boson using the same final state have been reported before by CDF [13,14] and D0 [15] with data corresponding to an integrated luminosity of 5.6 fb −1 and 5.3 fb −1 , respectively. Compared to the previously reported analysis, we have employed a Bayesian artificial neural network (BNN) discriminant [16,17] to improve discrimination between signal and background.…”

“…For dijet data, a jet [4] with transverse momentum p T > 20 GeV and |η| < 2.5 is selected, then a preselected EM cluster is selected in the opposite azimuthal plane with |∆φ(jet, EM)| > 2.9 radian as the jets misidentified as electrons or photons. To eliminate possible contamination from diboson, Z + jets and W + jets processes, events with at least one isolated high-p T muon [5], events with an invariant mass of the EM cluster and an isolated track between 60 and 120 GeV, and events with missing transverse energy [6] greater than 10 GeV are rejected. For studies of jets misidentified as photons, the γ + jet component containing a real photon is removed from the dijet sample by requiring that the EM cluster be nonisolated by cutting on the shower isolation fraction (see Sect.…”

The electron and photon reconstruction and identification algorithms used by the D0 Collaboration at the Fermilab Tevatron collider are described. The determination of the electron energy scale and resolution is presented. Studies of the performance of the electron and photon reconstruction and identification are summarized. The results are based on measurements of Z boson decay events of Z → ee and Z → γℓℓ (ℓ = e, µ) collected in pp collisions at a center-of-mass energy of 1.96 TeV using an integrated luminosity of up to 10 fb −1 .

“…We then perform the final normalization of the V þ jets and MJ backgrounds via a simultaneous fit to data in the M W T distribution after subtracting the other SM background predictions from the data as described in Refs.

“…The results presented here supersede previous searches by the D0 Collaboration, presented in Refs. [16][17][18][19][20], which used subsamples of the data presented in this article. They also supersede a previous search for Higgs boson production in the ' jj final state by the D0 Collaboration [21].…”

We present, in detail, a search for the standard model Higgs boson, H, in final states with a charged lepton (electron or muon), missing energy, and two or more jets in data corresponding to 9:7 fb À1 of integrated luminosity collected at a center-of-mass energy of ffiffi ffi s p ¼ 1:96 TeV with the D0 detector at the Fermilab Tevatron p " p Collider. The search uses b-jet identification to categorize events for improved signal versus background separation and is sensitive to associated production of the H with a W boson,b; gluon fusion with the Higgs decaying to W-boson pairs, H ! WW ! ' jj; and associated production with a vector boson where the Higgs decays to W-boson pairs, VH ! VWW ! ' jjjj production (where V ¼ W or Z). We observe good agreement between data and expected background. We test our method by measuring WZ and ZZ production with Z ! b " b and find production rates consistent with the standard model prediction. For a Higgs boson mass of 125 GeV, we set a 95% C.L. upper limit on the production of a standard model Higgs boson of 5:8 Â SM , where SM is the standard model Higgs boson production cross section, while the expected limit is 4:7 Â SM . We also interpret the data considering models with fourth generation fermions, or a fermiophobic Higgs boson.
