Study of Decays in the PQCD Factorization Approach with Lattice QCD Input

Figure 1

Theoretical predictions of the relevant form factors for transition in the PQCD approach (red curves) and the “PQCD+Lattice” approach (blue curves). The red (blue) shaded band represents the theory uncertainties. The black error bars in the low- region correspond to the PQCD predictions. The error bars in high- region are the lattice QCD results.
