通过给出味单态伪标量介子产生的结果,我们完成了在领先扭曲-2能级下对深度虚介子细产生过程的硬散射幅度的微扰次导级修正。新的结果是在公共动量分数表示和共形矩表示下给出的。我们还对深度虚化矢量介子产生的味道单态结果进行了评论。
We complete the perturbative next-to-leading order corrections to the hard scattering amplitudes of deeply virtual meson leptoproduction processes at leading twist-two level by presenting the results for the production of flavor singlet pseudoscalar mesons. The new results are given in the common momentum fraction representation and in terms of conformal moments. We also comment on the flavor singlet results for deeply virtual vector meson production.
