Violation Measurement

The Belle experiment has started in 1999 and has collected more than 600 fb-1 data at the ϒ(4S) resonance with the KEK-B asymmetric energy e+e- collider. In this contribution, the results of CP-violation measurement in B meson decays are presented. The large CP asymmetry arises thorough the interference between [Formula: see text] mixing and decay. The results yield constraints on the angles of the unitarity triangle, which is related to the Kobayashi-Maskawa quark mixing matrix. We discuss the status of the measurements on ϕ1, ϕ2 and ϕ3 with various methods.

We report a measurement of the CP violating asymmetry in D0 → π+π- decays using approximately 215,000 decays reconstructed in about 5.94 fb-1 of CDF data. We use the strong D⋆+ → D0π+ decay ("D⋆ tag") to identify the flavor of the charmed meson at production time and exploit CP-conserving strong [Formula: see text] pair-production in [Formula: see text] collisions. Higher statistic samples of Cabibbo-favored D0 → K-π+ decays with and without D⋆ tag are used to highly suppress systematic uncertainties due to detector effects. The result, ACP(D0 → π+π-) = [0.22 ± 0.24 (stat.) ± 0.11 (syst.)]%, is the world's most precise measurement to date and it is fully consistent with no CP violation.

In this paper, we study the combined sensitivity of T2K-II and NOvA, the world leading long-baseline neutrino oscillation experiments, to CP violation in lepton sector. By operating until the year 2026, T2K-II is expected to collect a total exposure of \(20 \times 10^{21}\) protons-on-target. Meanwhile, NO$\nu$A experiment plan to expend the run up to 2024. By combining T2K-II and NO\(\nu\)A with an ultimate constraint from reactor, the sensitivity to CP-violation is expected to exceed $4\sigma$ C.L. It is also pointed out that by reducing the systematic uncertainties of both T2K-II and NO$\nu$A to a level of  2\%, the sensitivity to CP-violation will significantly increase with a discovery possibility at 5$\sigma$ C.L. significance for a particular range of true \(\delta_{CP}\).
