Findings

Results agree with experimental data for various B decays.

Model effectively describes both heavy-to-heavy and heavy-to-light transitions.

Satisfies heavy quark effective theory constraints.

Abstract

Exclusive nonleptonic bottom meson decays are studied in the covariant osillator quark model using the factorization assumption. The main feature of this model is that it can simultaniously be applied to both heavy to heavy and heavy to 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.
