【 摘 要 】

This dissertation describes the measurement of branching fractions and CP asymmetries in neutral B meson decays to charmless two-body final states of charged pions and kaons. CP violation is a poorly-constrained phenomenon in the Standard model (SM) of particle physics and had been studied only in the kaon system before the Babar and Belle experiments. The decay of the neutral B meson to charged pions and kaons is particularly useful for the study of CP violation because they can be related to the Unitarity Triangle angle {alpha}.
