稀有B_c ~->D^*_s l^+ l^-衰变超出标准模型的一般分析

General analysis of the rare Bc->D^*_s l^+ l^- decay beyond the standard model

U. O. Yilmaz, G. Turan

摘要:

本文利用最一般的、与模型无关的有效哈密顿量,给出了稀有的Bc->D^*_sl ^+ l^-衰变的一般分析.研究了分支比、l^-的纵向、法向和横向偏振不对称性以及l^-和l^+的组合不对称性对新Wilson系数的依赖关系。我们的分析表明轻子极化不对称性对标量和张量型相互作用非常敏感,这对于寻找标准模型之外的新物理是非常有用的。

英文摘要:

The general analysis of the rare Bc->D^*_s l^+ l^- decay is presented by using the most general, model independent effective Hamiltonian. The dependencies of the branching ratios, longitudinal, normal and transversal polarization asymmetries for l^- and the combined asymmetries for l^- and l^+ on the new Wilson coefficients are investigated. Our analysis shows that the lepton polarization asymmetries are very sensitive to the scalar and tensor type interactions, which will be very useful in looking for new physics beyond the standard model.
