英文摘要 | The b -> d transition form factor (tff) f(+)(b -> d)(q(2)) is determined mainly by the d-meson leadingtwist distribution amplitude (da), phi(2; d), if the proper chiral current correlation function is adopted within the light-cone qcd sum rules. it is therefore significant to make a comprehensive study of da phi(2; d) and its impact on f(+)(b -> d)(q(2)). in this paper, we calculate the moments of phi(2; d) with the qcd sum rules under the framework of the background field theory. new sum rules for the leading-twist da moments |
