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…

A Note on Pretzelosity TMD Parton Distribution
X. P. Chai, K. B. Chen, J. P. Ma
We show that the transverse-momentum-dependent parton distribution, called as Pretzelosity function, is zero at any order in perturbation theory of QCD for a single massless quark…
