Nucleon-nucleon scattering up to next-to-leading order in manifestly Lorentz-invariant chiral effective field theory: low phases and the deuteron
Xiu-Lei Ren, E. Epelbaum, J. Gegelia
Recently the nucleon-nucleon interaction derived using time-ordered perturbation theory in manifestly Lorentz-invariant chiral effective field theory was shown to yield promising r…
Can the strong interactions between hadrons be determined using femtoscopy?
Evgeny Epelbaum, Sven Heihoff, Ulf-G. MeiÃner +2
In the last decades, femtoscopic measurements from heavy-ion collisions have become a popular tool to investigate the strong interactions between hadrons. The key observables measu…
On the definition of the nucleon axial charge density
J. Yu. Panteleeva, E. Epelbaum, J. Gegelia +1
We work out the spatial density distributions corresponding to the axial-vector charge density operator for spin-1/2 systems using states described by sharply localized wave packet…
Hadron Physics Opportunities at FAIR
J. G. Messchendorp, F. Nerling, P. Achenbach +103
This White Paper outlines a coordinated, decade-spanning programme of hadron and QCD studies anchored at the GSI/FAIR accelerator complex. Profiting from intense deuteron, proton a…
Subleading D-like Three-Nucleon Interactions
Henri Paul Huesmann, Hermann Krebs, Evgeny Epelbaum
We consider subleading contributions to the three-nucleon force from tree-level diagrams involving a single-pion exchange and a contact interaction between two nucleons, which appe…
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…
