Scrutiny of the new class of three-nucleon forces
E. Epelbaum, A. M. Gasparyan, J. Gegelia +2
In a recent publication, Cirigliano {\it et al.} [Phys. Rev. Lett. 135, 022501 (2025)] argue that three-nucleon forces (3NFs) involving short-range operators that couple two pions…
Subleading D-like Three-Nucleon Interactions
Henri Paul Huesmann, Hermann Krebs, Evgeny Epelbaum
We consider subleading contributions to the three-nucleon force from tree-level diagrams involving a single-pion exchange and a contact interaction between two nucleons, which appe…
Ab initio charge form factors and radii of light isoscalar nuclei: Role of the two-body charge density
Xiang-Xiang Sun, Vadim Baru, Arseniy A. Filin +4
We make \textit{ab initio} predictions of charge form factors (FFs) and radii for the isoscalar nuclei Li and Be using the Jacobi-coordinate No-Core Shell Model. The calcul…
Chiral -exchange potential using the method of unitary transformation
Victor Springer, Hermann Krebs, Evgeny Epelbaum
Nuclear potentials are known to exhibit a considerable degree of scheme dependence. For one- and two-pion exchange nucleon-nucleon (NN) potentials, unitary ambiguities start showin…
Non-perturbative three-nucleon simulation using chiral lattice EFT
Lukas Bovermann, Evgeny Epelbaum, Hermann Krebs +1
We study the three-nucleon system at next-to-next-to-next-to-leading order () in the framework of chiral effective field theory (EFT) on the lattice. Our calculatio…
