Abstract: (arXiv)

The module for the generation of

B_c

meson decays into

J/\psi + n\pi

and

B_s^{(*)} + n\pi

(

n\le 4

) is implemented into EvtGen program package. The decay amplitudes are calculated in the frame work of factorization model. Within this approach the decay can be represented as

B_c

decay into

J/\psi (B_s)+W^*

followed by the virtual

W^*

-boson decay into the final set of

\pi

-mesons. The described calculation technique allows to adopt the parameters of

W^*\to n\pi

transition from the analysis of

\tau

decay into

\nu_\tau+n\pi

. Comparison with available theoretical predictions is performed.

B/c: hadronic decay
Monte Carlo
charmonium
programming
pi: final state
W: intermediate state
W: decay
quantum chromodynamics: sum rule
B/c: form factor
quantum chromodynamics: factorization
