On Differences Between SCET and QCDF for B->pi pi Decays
  We give a detailed description of the differences between the factorization and results derived from SCET and QCDF for decays B -> M1 M2. This serves as a reply to a comment about our work "B-> M1 M2: Factorization, charming penguins, strong phases, and polarization" [1] made by the authors in [2]. We disagree with their criticisms.
