Abstract

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 9.7fb-1 of pp¯ collisions at s=1.96TeV collected with the D0 detector at the Fermilab Tevatron Collider. These are the first studies of Higgs boson JP with fermions in the final state. In the ZH→ bb¯, WH→ νbb¯, and ZH→ννbb¯ final states, we compare the standard model (SM) Higgs boson prediction, JP=0+, with two alternative hypotheses, JP=0- and JP=2+. We use a likelihood ratio to quantify the degree to which our data are incompatible with non-SM JP 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 JP=0- and JP=2+ hypotheses at the 97.6% CL and at the 99.0% CL, respectively. The expected exclusion sensitivity for a JP=0- (JP=2+) state is at the 99.86% (99.94%) CL. Under the hypothesis that our data are the result of a combination of the SM-like Higgs boson and either a JP=0- or a JP=2+ signal, we exclude a JP=0- fraction above 0.80 and a JP=2+ fraction above 0.67 at the 95% CL. The expected exclusion covers JP=0- (JP=2+) fractions above 0.54 (0.47).
