英文摘要	Within the framework of the b-meson light-cone sum rules, we review the calculation of radiative corrections to the three b -> pi transition form factors at leading power in lambda/m(b). to resum large logarithmic terms, we perform the complete renormalization group evolution of the correlation function. we employ the integral transformation which diagonalizes evolution equations of the jet function and the b-meson lightcone distribution amplitude to solve these evolution equations and obtain renormalization group improved sum rules for the b -> pi form factors. results of the form factors are extrapolated to the whole physical q(2) region and are compared with that of other approaches. the effect of b-meson three-particle light-cone distribution amplitudes, which will contribute to the form factors at next-to-leading power in lambda/m(b) at tree level, is not considered in this paper.
