NRQM中产生底介子衰变的粲轴矢量和赝标介子

Charmed Axial Vector and Pseudoscalar Mesons Emitting Decays of Bottom Meson in NRQM

Neelesh Sharma, Rohit Dhir

摘要:

利用非相对论夸克模型研究了底介子到赝标介子和轴矢量介子的两体非轻子弱衰变。我们利用因子分解假设计算了这些衰变的分支比。所得结果与已有的实验数据吻合较好。我们还计算了重夸克对称性约束下的分支比,并与已有的理论分析进行了比较。

英文摘要:

Two body nonleptonic weak decays of bottom mesons to a pseudoscalar meson and an axial-vector meson involving charmed states are studied using the non-relativistic quark model. We calculate the branching ratios of these decays by employing the factorization hypothesis. Obtained results are in good agreement with the existing experimental data. We also calculated the branching ratios in the light of heavy quark symmetry constraints and compared with the exiting theoretical analyses.
