We report the measurement of the asymmetry $A_{CP}$ of the branching fractions of $D^0\rightarrow K^-\pi^+$ in the CP-odd and CP-even eigenstates using a data sample of $2.92$ fb$^{-1}$ collected with the BESIII detector at the center-of-mass energy $\sqrt{s}=3.773$ GeV. With the measured $A_{CP}$ the...

Recent astrophysical observations are consistent with the existence of a secluded dark gauge sector weakly interacting with the Standard Model. The mass of the mediator, the so called dark photon, or U boson, is predicted to be at the GeV scale. Possible extensions of the minimal model lead to the introduction of a dark Higgs boson which, analogously to its Standard Model counterpart, breaks...

80. Measurements of CP violation at Belle

We present some of the recent measurements of $CP$ violation in $B$ decays based on the full data sample containing 772 million $B$ meson pairs collected at the $\Upsilon(4S)$ resonance using the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. In particular, we present measurements of time-dependent $CP$ violation parameters in $B^0 \to \eta'K^0$, $B^0 \to \omega K^0_S$...
