We present measurements of time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurement uses a data sample of 23 million Upsilon(4S)-->B-anti-B decays collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we find events where one neutral B meson is fully reconstructed in a CP eigenstate containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the Standard Model is proportional to sin2beta, is derived from the decay time distributions in such events. The result is sin2beta=0.34 +/- 0.20 (stat) +/- 0.05 (syst).

Discussion (0). Continue with ORCID to comment.

  1. $CP$ asymmetries in the $\Lambda_c^+\to pK^0_S$ and $\Xi^+_c\to \Sigma^+K^0_S$ decays

    hep-ph 2025-09 conditional novelty 5.0 of 10

    The Xi_c+ to Sigma+ K0_S decay can show an interference-induced CP asymmetry up to about 10^-3, several times larger than in D meson decays.

  2. Implications on CP violation of charmless three body decays of bottom baryon from the U-spin analysis

    hep-ph 2024-11 conditional novelty 5.0 of 10

    U-spin symmetry converts recent LHCb CP-violation measurements in Lambda_b charmless three-body decays into CP-asymmetry predictions for Xi_b^0 and Sigma^0 channels, plus a null test for the Standard Model.

  3. Study of $\Lambda^0_b \to \Lambda D$ decays with the rescattering mechanism

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    Rescattering enhances the anti-D0 Lambda branching fraction by two orders of magnitude and produces large direct CP asymmetries (0.28 and -0.14) in Lambda_b to Lambda D channels.
