摘要In this paper, we study the properties of the twist-3 distribution amplitude (DA) of the heavy pseudoscalars such as eta(c), B-c, and eta(b). New sum rules for the twist-3 DA moments (HP) and (HP) up to sixth order and up to dimension-six condensates are deduced under the framework of the background field theory. Based on the sum rules for the twist-3 DA moments, we construct a new model for the two twist-3 DAs of the heavy pseudoscalar with the help of the Brodsky-Huang-Lepage prescription. Furthermore, we apply them to the B-c -> eta(c) transition form factor (f(+)(Bc ->eta c)(q(2))) within the light-cone sum rules approach, and the results are comparable with other approaches. It has been found that the twist-3 DAs phi(P)(3;eta c) and phi(sigma)(3;eta c) are important for a reliable prediction of f(+)(Bc ->eta c) (q(2)). For example, at the maximum recoil region, we have f(+)(Bc ->eta c) (0) = 0.674 +/- 0.066, in which those two twist-3 terms provide similar to 33 and similar to 22% contributions. Also we calculate the branching ratio of the semi-leptonic decay B-c -> eta(c)l nu as Br(B-c -> eta(c)l nu) = (9.31(-2.01)(+2.27)) x 10(-3).
