In this work, we suggest that hard-pion chiral perturbation theory may be applicable to the real parts of nonleptonic B+ → D0P+ and B+ → D0P+ (P = K,π) decay amplitudes. These amplitudes play an important role in the extraction of the angle γ in the b−d unitarity triangle of the CKM matrix, and their real parts can be computed using lattice QCD. We construct the leading-order operator in the chiral expansion for these nonleptonic decays, and discuss the generic features of the next-to-leading-order terms.
