Measurement of the branching fraction of $B^+ \to \rho^+\rho^0$

We present a measurement of the branching fraction, the fraction of longitudinally polarized events and charge asymmetry of the decay $B^+ \to \rho^+\rho^0$. The data set for this analysis was recorded with the BaBar detector and corresponds to $210.5~{\rm fb}^{-1}$ (231 million $B\overline{B}$ pairs).
