Quantum coherent measurements

Abstract

The basic physics of quantum-correlated D 0 ,D 0 pairs produced at threshold via decays of the ψ(3770) is introduced. The connection to extractions of the CKM angle γ(φ 3 ) from B decays is emphasized throughout. Recent quantum correlation results from BESIII and CLEO-c are then summarized before closing with a discussion of selected issues.

Overview of the CP violation and mixing in the charm sector

“…The model-independent techniques are a very attractive possibility because the modelling of the Dalitz plot is associated with irreducible systematics due to the amplitude model. The uncertainty on the external measurements used in the model-independent techniques can be reduced further by using input from the experiment BESIII which is currently taking data, and a new measurement of the relative strong-phase difference parameters is underway, based on a sample four times bigger than the one collected by CLEO-c [15,16]. Moreover, this data sample is expected to grow by a factor of ten.…”
