光子相互作用和手征动力学

Photon interactions and chiral dynamics

Wojciech Broniowski, Alexandr E. Dorokhov, Enrique Ruiz Arriola

摘要:

在几种手征夸克模型中评估了实光子和虚光子分布振幅的Twist-2分量。在夸克模型尺度下得到的结果,然后演化到更高的尺度,在实验或格点量子色动力学中进行探测。我们还分析了相关的形状因子和耦合常数。我们的结果是一个真正的动力学预测,从手征动力学。

英文摘要:

Twist-2 components of the real and virtual photon distribution amplitudes are evaluated in several chiral quark models. The results, obtained at the quark model scale, are then evolved to higher scales, probed in experiments or in lattice QCD. We also analyze the related form factors and coupling constants. Our results are a genuine dynamical prediction, following from the chiral dynamics.
