QCD scales and chiral symmetry in finite nuclei [PDF]

, 1997
The authors report on this progress in the calculation of nuclear ground-state properties using effective Lagrangians whose construction is constrained by QCD scales and chiral symmetry. Good evidence is found that QCD and chiral symmetry apply to finite

Hadronic light-by-light contribution to aμ: extended Nambu-Jona-Lasinio, chiral quark models and chiral Lagrangians

EPJ Web of Conferences, 2016
This talk discusses our old work on the hadronic light-by-light contribution to the muon anomalous magnetic moment and some more recent contributions. I discuss the various contributions starting with pseudoscalar meson exchange, the quark- and pion-loop,

The phi NN coupling from chiral loops

, 2015
Starting from effective Lagrangians which combine a gauge formulation of Vector Meson Dominance with Chiral Lagrangians, the coupling of the phi to the nucleon, which is zero at tree level due to the OZI rule, is calculated perturbatively considering ...

Meson–meson and meson–baryon interactions in a chiral non-perturbative approach [PDF]

, 1998
A qualitative account of the meson-meson and meson-baryon interactions using chiral Lagrangians and the inverse amplitude method in coupled channels is done.

Chiral Anomalies and the Chiral Lagrangian [PDF]

, 1985
The subject of this thesis is some implications of chiral anomalies for chiral Lagrangians. The thesis consists of three parts: In the first part, a somewhat heuristic discussion of the topological meaning of anomalies is given in the framework ...

Vector two-point functions in finite volume using partially quenched chiral perturbation theory at two loops

Journal of High Energy Physics, 2017
We calculate vector-vector correlation functions at two loops using partially quenched chiral perturbation theory including finite volume effects and twisted boundary conditions.

WZW terms without anomalies: Generalised symmetries in chiral Lagrangians

SciPost Physics
We consider a 4d non-linear sigma model on the coset $(\text{SU}(N)_L × \text{SU}(N)_R × \text{SU}(2))/(\text{SU}(N)_{L+R}× \mathrm{U}(1))\cong \text{SU}(N) × S^2$, that features a topological Wess–Zumino–Witten (WZW) term whose curvature is $\frac{n}{24\
