Non-perturbative flavor asymmetry in the nucleon and deuteron: The light-front Hamiltonian effective field theory approach
Xianghui Cao, Shan Cheng, Yihan Duan +3
We investigate non-perturbative multi-pion contributions to nucleon flavor asymmetry within the framework of Light-Front Hamiltonian Effective Field Theory (LFHEFT). Utilizing a Fo…

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…
