Delta-excitations and the three-nucleon force
E. Epelbaum, H. Krebs, Ulf-G. Meißner
We study the three-nucleon force in chiral effective field theory with explicit Delta-resonance degrees of freedom. We show that up to next-to-next-to-leading order, the only contr…
Subleading contributions to the chiral three-nucleon force I: long-range terms
V. Bernard, E. Epelbaum, H. Krebs +1
We derive the long-range contributions to the tree-nucleon force at next-to-next-to-next-to-leading order in the chiral expansion. We give both momentum and coordinate space repres…
Dilute neutron matter on the lattice at next-to-leading order in chiral effective field theory
Bugra Borasoy, Evgeny Epelbaum, Hermann Krebs +2
We discuss lattice simulations of the ground state of dilute neutron matter at next-to-leading order in chiral effective field theory. In a previous paper the coefficients of the n…
Chiral effective field theory on the lattice at next-to-leading order
Bugra Borasoy, Evgeny Epelbaum, Hermann Krebs +2
We study nucleon-nucleon scattering on the lattice at next-to-leading order in chiral effective field theory. We determine phase shifts and mixing angles from the properties of two…
Two-particle scattering on the lattice: Phase shifts, spin-orbit coupling, and mixing angles
Bugra Borasoy, Evgeny Epelbaum, Hermann Krebs +2
We determine two-particle scattering phase shifts and mixing angles for quantum theories defined with lattice regularization. The method is suitable for any nonrelativistic effecti…
Nuclear forces with Delta-excitations up to next-to-next-to-leading order I: peripheral nucleon-nucleon waves
Hermann Krebs, Evgeny Epelbaum, Ulf-G. Meißner
We study the two-nucleon force at next-to-next-to-leading order in a chiral effective field theory with explicit Delta degrees of freedom. Fixing the appearing low-energy constants…
