Description
The BaBar experiment pioneered the low-energy, high-intensity collider search in various signatures of light dark matter and put stringent constraints on dark sector models. We present a new measurement, which focuses on the search for invisible decays of the dark photon.
We present results of a new analysis campaign, which combines the final data samples collected by the B factory experiments BaBar and Belle in single physics analyses to achieve a unique sensitivity in time-dependent CP violation measurements. We present a measurement of $\sin(2\beta)$ and $\cos(2\beta)$ by a time-dependent Dalitz plot analysis of $B^{0} \to D^{(*)} h^{0}$ with $D \to K_{S}^{0} \pi^{+} \pi^{-}$ decays. A first evidence for $\cos(2\beta)>0$, the exclusion of trigonometric multifold solutions of the Unitarity Triangle and an observation of CP violation are reported.
