We measure the B[sup 0] lifetime[tau][sub b[sup 0]] and the B[sup 0]-[bar B][sup 0] oscillation frequency[Delta]m[sub d] with a sample of approximately 14,000 e

The neutral B meson, consisting of a b quark and an anti-d quark, can mix (oscillate) to its own anti-particle through second-order weak interactions. The measu

The authors present a simultaneous measurement of the {bar B}° lifetime [tau](B°) and mixing parameter [Delta]m{sub d}. They use a sample of about 50000 {bar

The Standard Model of particle physics describes the fundamental building blocks of the Universe and their basic interactions. The model naturally describes the
