A. V. Berezhnoy, A. K. Likhoded, A. V. Luchinsky

摘要:

在因子分解模型的框架下计算了Bc → J/psi(Bs,Bs*)+ n π介子的衰变振幅,该模型可以将这一过程表示为Bc衰变到J/psi Bs+W*,然后虚W* 玻色子衰变到最终的π介子集合。在LHCb合作组的GAUSS程序包中实现了产生B_c介子衰变为J/psi + n π和Bs(*)+ n π(n <= 3)的模块。

英文摘要:

The Bc -> J/psi(Bs,Bs*)+ n pi decay amplitudes are calculated in the frame work of factorization model, which allows to represent this processes as Bc decay into J/psi Bs+W* followed by the virtual W*-boson decay into the final set of pi mesons. The module for the generation of Bc meson decays into J/psi + n pi and Bs(*) + n pi (n <= 3) is implemented into the GAUSS program package of the LHCb Collaboration.
