Convergence in charmonium structure: light-front wave functions from basis light-front quantization and Dyson-Schwinger equations

Xianghui Cao, Yang Li, Chao Shi +2

We present a systematic comparison of charmonium light-front wave functions obtained through two complementary non-perturbative approaches: Basis Light-Front Quantization (BLFQ) an…

Relativistic dynamics of charmonia in strong magnetic fields

Liuyuan Wen, Meijian Li, Yiyu Zhou +2

We investigate the properties of charmonium systems in strong external magnetic fields using a relativistic light-front Hamiltonian approach within the Basis Light-Front Quantizati…

Gravitational form factor of charmonium from shear stress

Tianyang Hu, Xianghui Cao, Siqi Xu +3

Based on our recent analysis of the hadronic matrix element of the stress-energy tensor in covariant light front dynamics, we extract the charmonium gravitational form factor $D(Q^…

Dissecting a strongly coupled scalar nucleon

Xianghui Cao, Yang Li, James P. Vary

We continue our investigation of the stress within a strongly coupled scalar nucleon, and now dissect the gravitational form factors into contributions from its constituents, the (…

Flavor asymmetry from the non-perturbative nucleon sea

Yihan Duan, Siqi Xu, Shan Cheng +3

We demonstrate, in the context of a scalar version of the chiral effective field theory, that the multi-sea quark contribution to the nucleon is significant and highly non-trivial…
