Polarization Effects in B -> K₁(1270) + J/Psi Decays

The joint angular distribution of the decay B \to J/\Psi V, where V is an axial vector or vector resonance, followed by the subsequent decay processes of the J/\Psi and V is calculated using the covariant density method. In particular, the case where V is the axial vector meson K_1(1270) which decays into K \rho is considered as well as the case that V is the vector meson K^\ast(890) which decays into K \pi.
