Nuclear pairing from chiral pion-nucleon dynamics
We use a recently improved version of the chiral nucleon-nucleon potential at next-to-next-toleading order to calculate the S0 pairing gap in isospin-symmetric nuclear matter. The pairing potential consists of the long-range oneand two-pion exchange terms and two short-distance NN-contact couplings. We find that the inclusion of the two-pion exchange at next-to-next-toleading order reduces subs...
متن کاملChiral Dymamics of Many Pion Systems: the Ρ → 4π and Ω → 5π Decays.
Based on the Weinberg lagrangian or, in a new language, the lagrangian of hidden local symmetry added with the term induced by the anomalous lagrangian of Wess and Zumino, the dynamics of the decays ρ → 4π and ω → 5π is considered. The excitation curves of ρ resonance in its decay to 4π are obtained for the first time.
متن کاملIsovector nuclear spin-orbit interaction from chiral pion-nucleon dynamics
Using the two-loop approximation of chiral perturbation theory, we calculate the momentum and density dependent isovector nuclear spin-orbit strength Vls(p, kf ). This quantity is derived from the spin-dependent part of the interaction energy Σspin = i 2 ~σ · (~q × ~ p )[Uls(p, kf ) − Vls(p, kf )τ3δ] of a nucleon scattering off weakly inhomogeneous isospinasymmetric nuclear matter. We find that...

Using the two-loop approximation of chiral perturbation theory, we calculate the momentum and density dependent nuclear spin-orbit strength Uls(p, kf ). This quantity is derived from the spin-dependent part of the interaction energy Σspin = i 2 ~σ ·(~q×~p )Uls(p, kf ) of a nucleon scattering off weakly inhomogeneous isospin symmetric nuclear matter. We find that iterated 1π-exchange generates a...
متن کاملChiral pion-nucleon dynamics in finite nuclei: spin-isospin excitations
The nuclear density functional framework, based on chiral dynamics and the symmetry breaking pattern of low-energy QCD, is extended to the description of collective nuclear excitations. Starting from the relativistic point-coupling Lagrangian introduced in Ref. [1], the proton-neutron (quasiparticle) random phase approximation is formulated and applied to investigate the role of chiral pion-nuc...
