Study of $B^+ \to \pi^+\pi^0 , K^+\pi^0$ decays

We present updated measurements of branching fractions and CP-violating asymmetries for charmless hadronic B-meson decays to the two-body final states $\pi^+\pi^0$ and $K^+\pi^0$. We use data collected with the BaBar detector at the PEP-II asymmetric energy $e^+e^-$ collider at SLAC.
