在本文中，我们证明了同时研究两个$\rho$-和$\pi$-介子生产的带电电流在Bjorken运动学允许一个非常干净的提取领先的扭曲广义Parton分布的目标，与固有的控制的贡献更高的扭曲修正。此外，它可能提供对所产生的介子的分布振幅的目标无关的约束。我们希望这种过程可以在中微子诱导或电子诱导的过程中进行研究。根据我们的数值估计，这些过程的横截面在JLab和EIC实验的范围内。
In this paper we prove that the simultaneous study of both $\rho$- and $\pi$-meson production by charged currents in Bjorken kinematics allows for a very clean extraction of the leading twist Generalized Parton Distributions of the target, with inherent control of the contribution of higher-twist corrections. Also, it might provide target-independent constraints on the distribution amplitudes of the produced mesons. We expect that such processes might be studied either in neutrino-induced or in electron-induced processes. According to our numerical estimates, the cross-sections of these processes are within the reach of JLab and EIC experiments.
