“…We find the resulting number of pretag and DT signal events for a SM Higgs to be 8.6 and 3.1 respectively, in agreement with the numbers listed in table 3 of [133]. We have also verified that we reproduce well the distribution of H + V invariant masses for the SM Higgs signal given by D0 in figure 2c of [73].…”

Constraints on the full set of Standard Model dimension-6 operators have previously used triple-gauge couplings to complement the constraints obtainable from Higgs signal strengths. Here we extend previous analyses of the Higgs sector constraints by including information from the associated production of Higgs and massive vector bosons (H+V production), which excludes a direction of limited sensitivity allowed by partial cancellations in the triple-gauge sector measured at LEP. Kinematic distributions in H+V production provide improved sensitivity to dimension-6 operators, as we illustrate here with simulations of the invariant mass and p T distributions measured by D0 and ATLAS, respectively. We provide bounds from a global fit to a complete set of CP-conserving operators affecting Higgs physics.

“…''b b analysis [23,24] requires two isolated charged leptons and at least two jets, at least one of which must pass a tight b-tagging requirement. A kinematic fit corrects the measured jet energies to their best fit values according to the constraints that the dilepton invariant mass should be consistent with the Z boson mass M Z and the total TABLE I.…”

“…All generators use the CTEQ6L1 [44,45] leading order (LO) parton distribution functions (PDF). Drell-Yan and W þ jets yields are normalized to next-to-next-to-LO (NNLO) calculations [46] or, in some analyses, to data control samples [23,24,26,28]. For the V þ b b=c c MC samples, generated separately from the V þ light-flavor events, we apply additional normalization factors calculated at next-to-LO (NLO) from MCFM [47,48] to account for the heavy-flavor to light-flavor production ratio.…”

We perform a combination of searches for standard model Higgs boson production in p p collisions recorded by the D0 detector at the Fermilab Tevatron Collider at a center of mass energy of ffiffi ffi s p ¼ 1:96 TeV. The different production and decay channels have been analyzed separately, with integrated luminosities of up to 9:7 fb À1 and for Higgs boson masses 90 M H 200 GeV. We combine these final states to achieve optimal sensitivity to the production of the Higgs boson. We also interpret the combination in terms of models with a fourth generation of fermions, and models with suppressed Higgs boson couplings to fermions. The result excludes a standard model Higgs boson at 95% C.L. in the ranges 90 < M H < 101 GeV and 157 < M H < 178 GeV, with an expected exclusion of 155 < M H < 175 GeV. In the range 120 < M H < 145 GeV, the data exhibit an excess over the expected background of up to 2 standard deviations, consistent with the presence of a standard model Higgs boson of mass 125 GeV.

“…To test compatibility of non-SM J P models with data, we use the D0 studies of ZH → llbb [18], WH → lνbb [19], and ZH → ννbb [20] with no modifications to the event selections. Lepton flavors considered in the WH → lνbb and ZH → llbb analyses include electrons and muons.…”

We present constraints on models containing non-standard model values for the spin J and parity P of the Higgs boson, H, in up to 9.7 fb −1 of pp collisions at √ s = 1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. These are the first studies of Higgs boson J P with fermions in the final state. In the ZH → ℓℓb b, W H → ℓνb b, and ZH → ννb b final states, we compare the standard model (SM) Higgs boson prediction, J P = 0 + , with two alternative hypotheses, J P = 0 − and J P = 2 + . We use a likelihood ratio to quantify the degree to which our data are incompatible with non-SM J P predictions for a range of possible production rates. Assuming that the production rate in the signal models considered is equal to the SM prediction, we reject the J P = 0 − and J P = 2 + hypotheses at the 97.6% CL and at the 99.0% CL, respectively. The expected exclusion sensitivity for a J P = 0 − (J P = 2 + ) state is at the 99.86% (99.94%) CL. Under the hypothesis that our data is the result of a combination of the SM-like Higgs boson and either a J P = 0 − or a J P = 2 + signal, we exclude a J P = 0 − fraction above 0.80 and a J P = 2 + fraction above 0.67 at the 95% CL. The expected exclusion covers J P = 0 − (J P = 2 + ) fractions above 0.54 (0.47).
