Constraints on Models of the Higgs Boson with Exotic Spin and Parity
using Decays to Bottom-Antibottom Quarks in the Full CDF Data Set

Περίληψη:
A search for particles with the same mass and couplings as those of the
standard model Higgs boson but different spin and parity quantum numbers
is presented. We test two specific alternative Higgs boson hypotheses: a
pseudoscalar Higgs boson with spin-parity J(P) = 0(-) and a gravitonlike
Higgs boson with J(P) = 2(+), assuming for both a mass of 125 GeV/c(2).
We search for these exotic states produced in association with a vector
boson and decaying into a bottom-antibottom quark pair. The vector boson
is reconstructed through its decay into an electron or muon pair, or an
electron or muon and a neutrino, or it is inferred from an imbalance in
total transverse momentum. We use expected kinematic differences between
events containing exotic Higgs bosons and those containing standard
model Higgs bosons. The data were collected by the CDF experiment at the
Tevatron proton-antiproton collider, operating at a center-of-mass
energy of root s = 1.96 TeV, and correspond to an integrated luminosity
of 9.45 fb(-1). We exclude deviations from the predictions of the
standard model with a Higgs boson of mass 125 GeV/c(2) at the level of 5
standard deviations, assuming signal strengths for exotic boson
production equal to the prediction for the standard model Higgs boson,
and set upper limits of approximately 30% relative to the standard
model rate on the possible rate of production of each exotic state.
