Measurement of strong phases, D– \overline{D} mixing, and CP violation using quantum correlation at charm threshold

Abstract

We review the measurements of the D decay strong-phase parameters based on quantum-correlated D⁰\overline{D}⁰ pairs produced in the e⁺e⁻ → Ψ(3770) → D⁰\overline{D}⁰ process, and we discuss their role in the measurements of Cabibbo-Kobayashi-Maskawa angle γ and D-\overline{D} mixing. In addition, we present estimates of the size of quantum-correlated datasets necessary to support the γ and charm mixing measurements conducted at the LHCb and Belle II experiments. Finally, we review the methods for measuring the D–\overline{D} mixing and CP violation parameters at a high-luminosity charm factory, giving sensitivity estimates.

[39] This estimate is meant to be indicative also because it neglects a number of differences in the underlying assumptions used by LHCb and Belle II.
