Polarization Effects in B -> K_1(1270) + J/ΨDecays

Abstract

The joint angular distribution of the decay B \to J/ΨV, where V is an axial vector or vector resonance, followed by the subsequent decay processes of the J/Ψand 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 ρis considered as well as the case that V is the vector meson K^\ast(890) which decays into K π.
