2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/48630We address a number of theoretical and phenomenological issues in two-body charmless non-leptonic B decays in the context of a factorization model. A classification of the exclusive decays involving tree and penguin amplitudes is reviewed. The role of QCD anomaly in exclusive decays involving an $η$ or $η'$ is elucidated and comparison is made with the existing data. We argue that the factorization approach accounts for most of the observed two-body B decays.7 pages (requires ltwol2e.sty, appended)High Energy Physics - Phenomenologytext
