摘要

Leading-twist distribution amplitudes (DAs) of light mesons like pi, rho etc. describe the leading nonperturbative hadronic contributions to exclusive QCD reactions at large energy transfer, for instance electromagnetic form factors. They also enter B decay amplitudes described in QCD factorisation, in particular nonleptonic two-body deca...更多
