Deeply virtual pion production through two-loop order
Wen Chen, Feng Feng, Yu Jia +3
Deeply virtual meson production (DVMP) is among the most prominent channels to extract the nucleon's generalized parton distributions (GPDs) at scattering facilities such as {…
Confronting perturbative QCD with the hardest exclusive reactions: kaon electromagnetic form factors
Long-Bin Chen, Wen Chen, Feng Feng +1
Among countless channels of hard exclusive reactions, the kaon electromagnetic form factors (EMFFs) are of special interest, which have been measured up to $Q^2 \sim 50\;{\rm GeV}^…
Next-to-leading-order QCD corrections to nucleon Dirac form factors
Long-Bin Chen, Wen Chen, Feng Feng +2
The leading-order perturbative QCD (pQCD) predictions to nucleon electromagnetic form factors were first made in late 70s. In this Letter for the first time we accomplish the calcu…
Next-to-next-to-leading-order QCD corrections to pion electromagnetic form factors
Long-Bin Chen, Wen Chen, Feng Feng +1
We investigate the next-to-next-to-leading order (NNLO) QCD radiative corrections to the pion electromagnetic form factor with large momentum transfer. We explicitly verify the val…
