Description
We present the results of two measurements that combine the integrated luminosity of about 1.1 inverse attobarn collected by the B factory experiments BaBar and Belle in single physics analyses. The first measurement is a time-dependent $CP$ violation measurement of $B^{0} \to D^{(*)}_{CP} h^{0}$ decays, where $h^{0}$ denotes a light neutral hadron and the $D_{CP}$ meson decays into two-body $CP$ eigenstates. A first observation of $CP$ violation governed by mixing-induced $CP$ violation according to $\sin{2\beta}$ is reported. The second presented measurement is a time-dependent Dalitz plot analysis of $B \to D^{(*)} h^{0}$ with $D \to K_{S}^{0} \pi^{+} \pi^{-}$ decays to access $\cos{2\beta}$. We report the first evidence for $\cos{2\beta}>0$ and the exclusion of multi-fold solutions of the CKM Unitarity Triangle.
