u通道颜色透明度可观测值

u-Channel Color Transparency Observables

G. M. Huber, W. B. Li, W. Cosyn, B. Pire

摘要:

我们建议研究的发病颜色透明的硬排他反应中的落后制度。在JLab关于中等Q^2下后向π介子和Ω电产生数据的令人鼓舞的结果的指导下,这可以解释为早期标度区域的信号,其中散射振幅分解为与核子到介子跃迁分布振幅卷积的硬系数函数,我们表明,对核靶上这些通道的研究为检验快速运动核子的核色透明现象提供了一个新的机会。

英文摘要:

We propose to study the onset of color transparency in hard exclusive reactions in the backward regime. Guided by the encouraging JLab results on backward pion and omega electro-production data at moderate Q^2, which may be interpreted as the signal of an early scaling regime where the scattering amplitude factorizes in a hard coefficient function convoluted with nucleon to meson transition distribution amplitudes, we show that the study of these channels on nuclear targets opens a new opportunity to test the appearance of nuclear color transparency for a fast moving nucleon.
