Light-cone Distribution Amplitudes of Vector Mesons within the Self-Consistent Light-front Quark Model
Xiao-Nan Li, Shuai Xu, Qin Chang
In this paper, we investigate the twist-2 and twist-3 light-cone distribution amplitudes (LCDAs) of vector mesons within the self-consistent light-front quark model, and the th…
Holographic Schwinger Effect In a Step Dilaton Background
Sara Tahery, Qin Chang
We investigate the holographic Schwinger effect in a confining background with a step dilaton profile, which induces a sharp transition between ultraviolet and infrared regimes and…
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…
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 , -m…
