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…
Shallow states from an EFT analysis of scattering on the lattice
Michael Abolnikov, Lu Meng, Vadim Baru +3
We present an effective field theory (EFT) framework for coupled-channel scattering, applying it to recent lattice QCD results by Alexandrou et al. [Phys. Rev…
Renormalizability and nonrenormalizability of nonlocal potentials
N. Jacobi, A. M. Gasparyan, E. Epelbaum
We consider separable toy models of the nucleon-nucleon interaction inspired by chiral effective field theory. We show that nonlocality of the long-range forces causes the need for…
Criteria of Renormalizability in Effective Field Theories
A. M. Gasparyan, E. Epelbaum
Any effective field theory relies on power counting rules that allow one to perform a systematic expansion of calculated quantities in terms of some soft scales. However, a naive p…
Left-hand cut problem in lattice QCD and an EFT-based solution
Lu Meng, Vadim Baru, Evgeny Epelbaum +2
Lattice QCD has become an essential tool for studying the hadron-hadron interaction from the first principles. However, when extracting infinite-volume scattering parameters from f…
Gravitational form factors of the deuteron
J. Yu. Panteleeva, E. Epelbaum, A. M. Gasparyan +1
The gravitational form factors of the deuteron are calculated in the framework of non-relativistic chiral effective field theory. Non-relativistic reduction of the matrix element o…
