A technique for improving the observation of CP-nonconservation inB 0 meson decays

In this paper, we show that it may be possible to increase the observability of the CP-violation inB ⁰-meson decays by measuring theB ⁰-meson decay rate as a function of time. We calculate the asymmetry in the time-dependent rate at which aB ⁰-meson and its conjugate particle decay to a given final state. We also calculate the time dependence of the decay rate asymmetry for a correlated \(B - \bar B\) pair. It is suggested that searches for CP-violation lose information by integrating away the time dependence. We then calculate the gain in signal strength from watching the evolution of theB-meson states as a function of time.
