Spectroscopic basis for short-range three-nucleon forces
Josep Solà Cava, Arseniy A. Filin, Sven Heihoff +2
The paper introduces a spectroscopic basis to classify subleading contact three‑nucleon forces by angular momentum and parity, and uses it to fit low‑energy constants from nucleon‑…
Exact emulation of few-body systems at low cost
Sven Heihoff, Arseniy A. Filin, Evgeny Epelbaum
Effective field theories have established themselves as key pillars of modern nuclear physics. They enable a quantitative understanding of the strong nuclear force, provided low-en…
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…
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…
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…
Internal structure of the from its light-quark mass dependence
Michael Abolnikov, Vadim Baru, Evgeny Epelbaum +3
We employ a chiral effective field theory-based approach to connect scattering observables at the physical and variable pion masses accessible in lattice QCD simulations. We…
