New results on Pionic Twist-3 Distribution Amplitudes within the QCD Sum Rules

Tao Zhong, Xing-Gang Wu, Jia-Wei Zhang +2

We present an improved calculation on the pionic twist-3 distribution amplitudes ${\varphi }_p^{\pi }$ and ${\varphi }_{\sigma }^{\pi }$, which are studied within the QCD sum rules. By adding all the uncertainties…
