2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/180001We compare the theoretical frameworks and the phenomenological applications of the factorization approaches to exclusive $B$ meson decays, which include QCD-improved factorization, perturbative QCD, and soft-collinear effective theory. Recent progress on two-body nonleptonic $B$ meson decays made in these approaches are reviewed.6 pages, 2 figures, more references added, Flavor Physics & CP Violation Conference, Bled, 2007High Energy Physics - Phenomenologytext
