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.

Bc 上的带电希格斯贡献 → (Ds, Ds*) l+l−

在本文中,我们在 I、II 和 III 型两个希格斯双峰模型的背景下研究了 B_c 介子的罕见半轻衰变。我们遵循相对论夸克模型来参数化在相应介子状态之间的弱跃迁矩阵元素中使用的形状因子。我们研究了诸如分支比、轻子极化不对称性、前后不对称性等可观察量,并分析了这些量对模型参数的依赖性。我们发现这些可观测物对带电希格斯玻色子具有明显的敏感性,这可能为标准模型和超越标准模型的新物理学提供有力的探索。
