Perturbative EFT calculation of the deuteron longitudinal response function
Andrew J. Andis, Songlin Lyu, Bingwei Long +1
In this work, we study the longitudinal response function of the deuteron up to next-to-next-to-leading order in chiral effective field theory (Chiral EFT). We use an approach that…
Simplification of chiral nuclear forces near the unitarity limit
Songlin Lyu, Lin Zuo, Rui Peng +2
Modern theory approaches for describing atomic nuclei often make use of on an effective theory that constructs the interaction between nucleons systematically based on Quantum Chro…
Perturbative renormalization of chiral nuclear forces at subleading order in 3S1-3D1 channel
Rui Peng, Bingwei Long, Fu-Rong Xu
We investigate renormalization of chiral nuclear forces in the coupled channel of 3S1-3D1 of nucleon-nucleon scattering. The one-pion exchange potential is treated nonperturbativel…
Systematic study of large-momentum distribution in nuclei with the operator product expansion
Jiexin Yu, Bingwei Long
The operator product expansion (OPE) is applied in conjunction with Pionless effective field theory to study the short-rang structure of nuclei. By matching the OPE with the select…
