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…
