Charged Current Single Pion Cross Section Measurement at MiniBooNE
  We present MiniBooNE's preliminary numu charged-current single pion (CC1pi) cross section measurement, calculated using the ratio to charge current quasi-elastic (CCQE) events. We find the inclusive CC1pi cross section to be below the predcition of the NUANCE and NEUGEN Monte Carlos.
