New ISR Cross Section Results on $e^+e^- \to π^+π^-π^0π^0$ and $e^+e^- \to π^+π^-η$ from BaBar

Abstract: Two new hadronic cross sections measured by the BaBar experiment are presented: $e^+e^- \to \pi^+\pi^-\pi^0\pi^0$ and $e^+e^- \to \pi^+\pi^-\eta$. For both channels, the contribution the anomalous magnetic moment of the muon is calculated.
