We present a measurement of the Standard Model CP violation parameter sin 2phi_1 based on a 29.1 fb^{-1} data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. One neutral B meson is fully reconstructed as a J/psi Ks, psi(2S) Ks, chi_c1 Ks, eta_c Ks, J/psi K_L or J/psi K^{*0} decay and the flavor of the accompanying B meson is identified from its decay products. From the asymmetry in the distribution of the time intervals between the two B meson decay points, we determine sin 2phi_1 = 0.99 +- 0.14(stat) +- 0.06(syst). We conclude that we have observed CP violation in the neutral B meson system.

First individual A_CP measurements for Xi_c+ -> Sigma+ h+h- and Lambda_c+ -> p h+h- decays, all consistent with CP symmetry and with U-spin sum-rule predictions.

Constraints on the mass of the dark antibaryon using $B_d\rightarrow \Lambda \psi_{DS}$ channel in light cone QCD
The mass ranges for the dark antibaryon ψ_DS are determined by deriving the B_d → Λ ψ_DS branching fraction via light-cone QCD sum rules and comparing it to BaBar and Belle experimental bounds.

Model-independent probes of CP violation in the heavy scalar sector at muon colliders
Observing vector boson fusion production of a heavy scalar followed by decay to Z h1 at muon colliders can establish CP violation in the scalar sector because it requires both h2VV and h2h1Z couplings to be nonzero.

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.

Full analysis of CP violation induced by the decay angular correlations in four-body cascade decays of heavy hadrons

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

CP violation observables in baryon decays
Time-reversal-odd CP observables in baryon decays are proportional to the cosine of strong-phase differences, so they complement sine-suppressed direct CP asymmetries.
