Towards consistent nuclear interactions from chiral Lagrangians II: Symmetry preserving regularization
Hermann Krebs, Evgeny Epelbaum
Low-energy nuclear structure and reactions can be described in a systematically improvable way using the framework of chiral effective field theory. This requires solving the quant…
Gravitational transition form factors in chiral perturbation theory
H. Alharazin, B. -D. Sun, E. Epelbaum +2
The gravitational form factors of the transition from the proton to the resonance are calculated to leading one-loop order using a manifestly Lorentz-invariant formulation of…
Solving the left-hand cut problem in lattice QCD: from finite volume energy levels
Lu Meng, Vadim Baru, Evgeny Epelbaum +2
We discuss a novel effective-field-theory-based approach for extracting two-body scattering information from finite volume energies, serving as an alternative to Lüscher's method.…
Towards consistent nuclear interactions from chiral Lagrangians I: The path-integral approach
Hermann Krebs, Evgeny Epelbaum
Low-energy nuclear interactions have been extensively studied in the framework of chiral effective field theory. The corresponding potentials have been worked out using dimensional…
Electromagnetic and gravitational local spatial densities for spin-1 systems
J. Yu. Panteleeva, E. Epelbaum, J. Gegelia +1
The matrix elements of the electromagnetic current and the energy-momentum tensor for sharply localized states of spin-1 systems are considered. Their interpretation as local spati…
Role of left-hand cut contributions on pole extractions from lattice data: Case study for
Meng-Lin Du, Arseniy Filin, Vadim Baru +7
We discuss recent lattice data for the state to stress, for the first time, a potentially strong impact of left-hand cuts from the one-pion exchange on the pole ex…
