TITLE: physics seminar / Search for the Higgs Boson Produced in Association with a Vector Boson Using Like-Sign Dilepton Events at CDF
CONTACT: Takasumi Maruyama
SPEAKER: Daisuke Yamato  (Osaka City University)
LANGUAGE: Japanese
ABSTRACT: We present a search for the neutral Higgs boson produced in associated
with a vector boson using high-pT isolated like-sign dilepton events
in proton-antiproton collisions at the center of energy 1.96 TeV.
The data were collected with the CDF-II detector at the Fermilab
Tevatron collider.
The integrated luminosity used in this analysis
corresponds to 9.4 fb^{-1}.
We employ the Boosted Decision Tree technique for separating the
backgrounds from signal events to improve the search sensitivity.
No signal is observed in the CDF data and we set limits on
the production rate of the Higgs boson in the standard model
and in an alternative fermiophobic (Higgs does not couple to fermion)
scenario.
