摘要:

考虑到扭曲3的贡献,我们评估了gamma* -> rhoT转变的影响因子。我们证明了借助QCD运动方程得到的规范不变表达式。我们的结果是自由的端点奇点。这开辟了一条道路,一致的治疗与横向极化矢量介子的排他性过程的因式分解。

英文摘要:

We evaluate the impact factor of the transition gamma* -> rhoT taking into account the twist 3 contributions. We show that a gauge invariant expression is obtained with the help of QCD equations of motion. Our results are free of end-point singularities. This opens the way to a consistent treatment of factorization for exclusive processes with a transversally polarized vector meson.
