Abstract

We discuss the relationship between the graphical amplitudes T, C, P, ⋯ used to parameterize non-leptonic B decay amplitudes, and matrix elements of operators in the soft-collinear effective theory (SCET) at leading order in Λ/mb. Using the SU(3) flavor symmetry of the weak Hamiltonian we derive all-order constraints on the Wilson coefficients of SCET operators.
