Decays of ground state Bc-meson Bc→J/ψ+nπ are considered. Using existing parametrizations for Bc→J/ψ form-factors and W∗→nπ spectral functions we calculate branching fractions and transferred momentum distributions of Bc→J/ψ+nπ decays for n=1,2,3,4. Inclusive decays Bc→J/ψ+uˉd and polarization asymmetries of final charmonium are also investigated. Presented in our article results can be used to study form-factors of Bc→J/ψ transitions, π-meson system spectral functions and give the opportunity to check the factorization theorem.
