Perturbative QCD Analysis of Near Threshold Heavy Quarkonium Photoproduction at Large Momentum Transfer
Peng Sun, Xuan-Bo Tong, Feng Yuan
We apply perturbative QCD to investigate the near threshold heavy quarkonium photoproduction at large momentum transfer. From an explicit calculation, we show that the conventional…

Gluon Gravitational Form Factors at Large Momentum Transfer
Xuan-Bo Tong, Jian-Ping Ma, Feng Yuan
We perform a perturbative QCD analysis of the gluonic gravitational form factors (GFFs) of the proton and pion at large momentum transfer. We derive the explicit factorization form…

Fracture Functions in Different Kinematic Regions and Their Factorizations
X. P. Chai, K. B. Chen, J. P. Ma +1
Fracture functions are parton distributions of an initial hadron in the presence of an almost collinear particle observed in the final state. They are important ingredients in QCD…
