Effective forces between quantum bound states

Alexander Rokash, Evgeny Epelbaum, Hermann Krebs +1

Recent ab initio lattice studies have found that the interactions between alpha particles (4He nuclei) are sensitive to seemingly minor details of the nucleon-nucleon force such as…

Nuclear axial current operators to fourth order in chiral effective field theory

H. Krebs, E. Epelbaum, U. -G. Meißner

We present the complete derivation of the nuclear axial charge and current operators as well as the pseudoscalar operators to fourth order in the chiral expansion relative to the d…

Reconciling threshold and subthreshold expansions for pion-nucleon scattering

D. Siemens, J. Ruiz de Elvira, E. Epelbaum +4

Heavy-baryon chiral perturbation theory (ChPT) at one loop fails in relating the pion-nucleon amplitude in the physical region and for subthreshold kinematics due to loop effects e…

Role of the total isospin 3/2 component in three-nucleon reactions

H. Witała, J. Golak, R. Skibiński +7

We discuss the role of the three-nucleon isospin T=3/2 amplitude in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude ori…

Testing semi-local chiral two-nucleon interaction in selected electroweak processes

R. Skibinski, J. Golak, K. Topolnicki +6

The recently developed semi-local improved chiral nucleon-nucleon interaction is used for the first time to study several electromagnetic and weak processes at energies below the p…

Pion-nucleon scattering in covariant baryon chiral perturbation theory with explicit Delta resonances

De-Liang Yao, D. Siemens, V. Bernard +5

We present the results of a third order calculation of the pion-nucleon scattering amplitude in a chiral effective field theory with pions, nucleons and delta resonances as explici…
