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…
Enhancement of deltaful two-pion exchange nuclear forces
Haiming Chen, Rui Peng, Songlin Lyu +1
The role of the delta isobar degrees of freedom in nucleon-nucleon scattering is revisited. We attempt to understand why the dimensionally regularized two-pion exchanges with the e…
Contact operators in renormalization of attractive singular potentials
Rui Peng, Bingwei Long, Fu-Rong Xu
We discuss renormalization of chiral nuclear forces in the 3P0 channel of N N scattering at next- to-next-to leading order (N2LO) if the one-pion exchange is treated nonperturbativ…
