It contains a single complex scalar doublet field, whose only observable article is the neutral Higgs boson. At present there are no experimental results that limit the Higgs sector to a single doublet. The authors search for evidence of a minimal extension to the Higgs sector, through the addition of a second scalar doublet. They examine predictions of a model that couples one doublet to up-type quarks and neutrinos, and the other to down-type quarks and charged leptons, as is the case for the minimal supersymmetric model. In conlusion, the authors find no evidence for a charged Higgs-boson in their data. 收起
