Non-leptonic two-meson decays of B mesons in the covariant oscillator quark model with factorization ansatz

Abstract

Exclusive nonleptonic bottom meson decays are studied in the covariant oscillator quark model using the factorization assumption. The main feature of this model is that it can simultaniously be applied to both heavy → heavy and heavy → light transitions, satisfying the constraints of the heavy quark effective theory (HQET) in the appropriate limit. The results obtained are in overall agreement with the present experimental data for various B decays.
