Non-leptonic B Meson Decays using Perturbative QCD

摘要

Using perturbative QCD within the framework of Szczepaniak et al. (1990), we analyse different non-leptonic B decays, namely B -> #pi##pi#, B -> #pi#(#KAPPA#)D, B -> DD, as heavy-to-light transitions dominated by tree diagrams and compare our estimates to experimental date and other theoretical model predictions.
