Angular momentum decomposition from a QED example
Tianbo Liu, Bo-Qiang Ma
We investigate the angular momentum decomposition with a quantum electrodynamics example to clarify the proton spin decomposition debates. We adopt the light-front formalism where…
Generalized form factors of the nucleon in a light-cone spectator-diquark model
Tianbo Liu, Bo-Qiang Ma
We investigate the generalized form factors of the nucleon in a light-cone spectator-diquark model. Compared to the form factors, the generalized form factors contain some more inf…
Quark orbital motions from Wigner distributions
Tianbo Liu
We investigate quark Wigner distributions in a light-cone spectator model. Both the scalar and the axial-vector spectators are included. The light-cone wave functions are derived f…
Present status on experimental search for pentaquarks
Tianbo Liu, Yajun Mao, Bo-Qiang Ma
It has been ten years since the first report for a positive strangeness pentaquark-like baryon state. However the existence of the pentaquark state is still controversial. Some con…
