Measurements of the branching fraction, polarization, and $CP$ asymmetry for the decay $B^0\to \omega \omega$

Belle Collaboration, Y. Guan, A. J. Schwartz +167

We present a measurement of $B^0\to \omega \omega$, a charmless decay into two vector mesons, using 772 $\times 10^6$ $B\overline{B}$ pairs collected with the Belle detector at the…
