Several Topics on Transverse Momentum-Dependent Fragmentation Functions
Kai-Bao Chen, Tianbo Liu, Yu-Kun Song +1
The hadronization of a high-energy parton is described by fragmentation functions which are introduced through QCD factorizations. While the hadronization mechanism per se remains…

We propose a six-dimensional light-front Wigner distribution for the complete description of partonic structures of a hadron such as pion and proton, taking advantage of the recent…
Towards a single scale-dependent Pomeron in holographic light-front QCD
Hans Günter Dosch, Guy F. de Téramond, Tianbo Liu +3
The Pomeron Regge trajectory underlies the dynamics dependence of hadronic total cross sections and diffractive reactions at high energies. The physics of the Pomeron is closely re…

Guy F. de Téramond, H. G. Dosch, Tianbo Liu +3
The holographic light-front QCD framework provides a unified nonperturbative description of the hadron mass spectrum, form factors and quark distributions. In this article we exten…
