We report on the first direct search for charged Higgs bosons decaying into cs in tt events produced by pp collisions at square root s = 1.96 TeV. The search uses a data sample corresponding to an integrated luminosity of 2.2 fb(-1) collected by the CDF II detector at Fermilab and looks for a resonance in the invariant mass distribution of two jets in the lepton + jets sample of tt candidates. We observe no evidence of charged Higgs bosons in top quark decays. Hence, 95% upper limits on the top quark decay branching ratio are placed at B(t --> H(+)b)< 0.1 to 0.3 for charged Higgs boson masses of 60 to 150 GeV/c(2) assuming B(H(+) --> cs)=1.0. The upper limits on B(t --> H(+)b) are also used as model-independent limits on the decay branching ratio of top quarks to generic scalar charged bosons beyond the standard model.
我们报告了在费米实验室的CDF II探测器收集的对应于2.2 fb⁻¹积分亮度的数据样本中，对质心能量√s = 1.96 TeV的质子-质子碰撞产生的tt事件中带电希格斯玻色子衰变为cs的首次直接搜索。该搜索在tt候选者的轻子+喷注样本中，寻找两个喷注的不变质量分布中的共振。我们未观察到顶夸克衰变中带电希格斯玻色子的证据。因此，假设B(H⁺→cs)=1.0，对于60至150 GeV/c²的带电希格斯玻色子质量，顶夸克衰变分支比的95%上限为B(t→H⁺b)<0.1至0.3。B(t→H⁺b)的上限也用作对超出标准模型的顶夸克到一般标量带电玻色子衰变分支比的与模型无关的限制。
