Decay-time-dependent C P -violation effects in transitions of neutral B mesons to C P -eigenstates can be visualised by oscillations in the asymmetry, as a function of decay time, between decay yields from mesons tagged as initially having B ¯ or B flavour. Such images, for example for B 0 → J / ψ K S 0 decays where the magnitude of the oscillation is proportional to sin (2 β) with β being an angle of the Cabibbo–Kobayashi–Maskawa Unitarity Triangle, provide a straightforward illustration of the underlying physics. Until now there has been no comparable method to provide visualisation for the case of decays to multibody final states that are not C P -eigenstates, where interference between C P -even and -odd amplitudes provides additional physics sensitivity. A method is proposed to weight the data so that the terms of interest can be projected out and used to obtain asymmetries that visualise the relevant effects. Application of the weighting to B s 0 decays, where effects due to non-zero width difference are not negligible, provides a novel method to observe C P violation in interference between mixing and decay without tagging the production flavour.

Moreover, as spokesperson of the Belle collaboration when the experiment was being constructed, collecting data, and producing key publications, Hiroaki Aihara is one of the best placed people to tell it. The asymmetric B factory collider experiments, BaBar and Belle, made a series of breakthrough particle physics measurements in the first decade of the 21 SP st sp century.

The current status of the determination of the elements of the Cabibbo-Kobayashi-Maskawa quark-mixing matrix is reviewed. Tensions in the global fits are highlighted. Particular attention is paid to the progress in, and prospects for, measurements of CP violation effects. [ABSTRACT FROM AUTHOR]
