Distribution Amplitudes of Pseudoscalar Mesons within the Light-Front Quark Model
Xiao-Nan Li, Shuai Xu, Qin Chang
In this paper, we investigate the distribution amplitudes (DAs) of pseudoscalar mesons within the light-front quark model (LFQM), and the -th Gegenbauer moment , -mom…

Quarkonium light-cone distribution amplitudes: twist structure and mass dependence
Shuai Xu, Xiao-Nan Li, Jin-Zhong Han +3
We present a systematic study of the leading- and next-to-leading-twist light-cone distribution amplitudes (LCDAs) of ground-state pseudoscalar and vector quarkonium within the lig…

The Electromagnetic Form Factors of Pseudoscalar Mesons within the Light-Front Quark Model
Shuai Xu, Xiao-Nan Li, Xing-Gang Wu
In this paper, we investigate the electromagnetic form factors (EMFFs) and charge radii of pseudoscalar mesons within the light-front quark model (LFQM). Using parameters derived f…
