Essential elements for nuclear binding
Bing-Nan Lu, Ning Li, Serdar Elhatisari +3
How does nuclear binding emerge from first principles? Our current best understanding of nuclear forces is based on a systematic low-energy expansion called chiral effective field…
How (not) to renormalize integral equations with singular potentials in effective field theory
E. Epelbaum, A. M. Gasparyan, J. Gegelia +1
We discuss the connection between the perturbative and non-perturbative renormalization and related conceptual issues in the few-nucleon sector of the low-energy effective field th…
Remarks on the Heavy-Quark Flavour Symmetry for doubly heavy hadronic molecules
V. Baru, E. Epelbaum, J. Gegelia +3
The possibility for a common effective field theory for hadronic molecules with different heavy-quark flavours is examined critically. It is argued that such a theory does not allo…
Few- and many-nucleon systems with semilocal coordinate-space regularized chiral two- and three-body forces
E. Epelbaum, J. Golak, K. Hebeler +12
We present a complete calculation of nucleon-deuteron scattering as well as ground and low-lying excited states of light nuclei in the mass range A=3-16 up through next-to-next-to-…
Neutron-proton scattering with lattice chiral effective field theory at next-to-next-to-next-to-leading order
Ning Li, Serdar Elhatisari, Evgeny Epelbaum +3
We present a new lattice formulation of chiral effective field theory interactions with a simpler decomposition into spin channels. With these interactions the process of fitting t…
Three-nucleon force in chiral EFT with explicit degrees of freedom: Longest-range contributions at fourth order
H. Krebs, A. M. Gasparyan, E. Epelbaum
We analyze the longest-range two-pion exchange contributions to the three-nucleon force at leading-loop order in the framework of heavy-baryon chiral effective field theory with ex…
