It has led to a precise determination of the elements V_/V_ of the Kobayashi-Maskawa matrix, providing a unique test of the Kobayashi-Maskawa theory of CP violation in weak interactions of elementary particles. The observation will also enable studies of CP-violation phenomena using the decay modes of the B^O_S meson that have not been explored previously.}, pages = {249--254}, title = {B^O_S中間子の粒子・反粒子振動の観測}, volume = {62}, year = {2007, 2009}, yomi = {ウケガワ, フミヒコ and キム, シンホン} }
