Abstract

Combined constraints from the CDF and D0 Collaborations on models of the Higgs boson withexotic spin J and parity Pare presented and compared with results obtained assuming the standardmodel valueJP= 0+. Both collaborations analyzed approximately 10 fb−1of proton-antiproton collisions with a center-of-mass energy of 1.96 TeV collected at the Fermilab Tevatron. Two modelspredicting exotic Higgs bosons withJP= 0−andJP= 2+are tested. The kinematic properties ofexotic Higgs boson production in association with a vector boson differ from those predicted for thestandard model Higgs boson. Upper limits at the 95% credibility level on the production rates ofthe exotic Higgs bosons, expressed as fractions of the standard model Higgs boson production rate,are set at 0.36 for both theJP= 0−hypothesis and theJP= 2+hypothesis. If the productionrate times the branching ratio to a bottom-antibottom pair is the same as that predicted for thestandard model Higgs boson, then the exotic bosons are excluded with significances of 5.0 standarddeviations and 4.9 standard deviations for theJP= 0−andJP= 2+hypotheses, respectively.
