论文摘要
在本文中，我们研究了在I型，II和III两个Higgs Doublet模型的背景下B_C介子的罕见半衰减衰变。我们遵循相对论的夸克模型，以参数化相应介子状态之间弱过渡的矩阵元素中使用的形式因素。我们研究了可观察到的物品，例如分支比率，Lepton极化不对称，前后不对称等，并分析这些数量对模型参数的依赖性。我们发现，这些可观察到的对带电的希格斯玻色子具有明显的敏感性，这可能会对标准模型和超越其新物理的强大探测。
In this paper, we study rare semileptonic decays of B_c meson in the context of type-I, II, and III two Higgs doublet model. We follow the relativistic quark model for parameterizing the form factors used in matrix elements of weak transitions between the corresponding meson states. We investigate the observables such as branching ratio, lepton polarization asymmetry, forward-backward asymmetry, etc. and analyze the dependence of these quantities on the model parameters. We have found that there are noticeable sensitivity of these observables for charged Higgs boson, which may provide a powerful probe to the standard model and new physics beyond it.
