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

Figure 2

Theoretical predictions for the -dependence of differential branching fraction for the semileptonic decays in the PQCD (red band) and “PQCD+Lattice” (blue band) approach, respectively. The crosses show the LHCb measurements in different bins as given in Reference [31] (orange ones) and in Reference [33] (black ones). The vertical grey blocks are the experimental veto regions.
