Abstract: (arXiv)

Decays of ground state

B_{c}

-meson

B_{c}\to J/\psi+n\pi

are considered. Using existing parametrizations for

B_{c}\to J/\psi

form-factors and

W^{*}\to n\pi

spectral functions we calculate branching fractions and transferred momentum distributions of

B_{c}\to J/\psi+n\pi

decays for

n=1,2,3,4

. Inclusive decays

B_{c}\to J/\psi+\bar{u}d

and polarization asymmetries of final charmonium are also investigated. Presented in our article results can be used to study form-factors of

B_{c}\to J/\psi

transitions,

\pi

-meson system spectral functions and give the opportunity to check the factorization theorem.
