We propose a new method for treating both nuclear and Coulomb breakup processes with high accuracy and computational speed. The scattering amplitude of breakup reaction is decomposed into the lower and higher partial-wave parts. The former is calculated with the continuum-discretized coupled-channels method (CDCC) and the latter with a new version of CDCC in which the trajectory of projectile is assumed to be a straight line. Validity of this hybrid calculation is tested for 58Ni(8B, 7Be+p) 58Ni at 240 MeV. The hybrid calculation is opening the door to the systematic analysis of 8B dissociation measured at RIKEN, MSU, and GSI, to determine the astrophysical factor S17(0) accurately.
