2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/40676We review the present status of rare B decays, focusing on inclusive decay modes and their role in our search for new physics. We also briefly discuss direct CP violation in rare B decays and the rare kaon decays $K^+\to π^+ν\barν$ and $K_L \to π^0 ν\barν$, which offer complementary opportunities for precision flavour physics.46 pages, latex, 17 figures, references addedHigh Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
