We report the results of a search for a charged Higgs boson in the decays of top quarks produced in p (p) over bar collisions at a center-of-mass energy of 1.96 TeV. We use a data sample corresponding to an integrated luminosity of 193 pb(-1) collected by the upgraded Collider Detector at Fermilab. No evidence for charged Higgs production is found, allowing 95% C.L. upper limits to be placed on BR(t -> H(+)b) for different charged Higgs decay scenarios. In addition, we present in the minimal supersymmetric standard model (m(H)(+/-),tan beta) plane the first exclusion regions with radiative and Yukawa coupling corrections.

Abstract
We report the results of a search for a charged Higgs boson in the decays of top quarks produced in p (p) over bar collisions at a center-of-mass energy of 1.96 TeV. We use a data sample corresponding to an integrated luminosity of 193 pb(-1) collected by the upgraded Collider Detector at Fermilab. No evidence for charged Higgs production is found, allowing 95% C.L. upper limits to be placed on BR(t -> H(+)b) for different charged Higgs decay scenarios. In addition, we present in the minimal supersymmetric standard model (m(H)(+/-),tan beta) plane the first exclusion regions with radiative and Yukawa coupling corrections.File in questo prodotto:
