We review the present status of the Standard Model calculation of the anomalous magnetic
moment of the muon. This is performed in a perturbative expansion in the fine-structure …

Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

In this review, we present the current state of the art of our understanding of the spectrum of
excited strongly interacting particles and discuss methods that allow for a systematic and …

A bstract In this third paper of a series dedicated to a dispersive treatment of the hadronic
light-by-light (HLbL) tensor, we derive a partial-wave formulation for two-pion intermediate …

The existence and properties of the sigma meson have been controversial for almost six
decades, despite playing a central role in the spontaneous chiral symmetry of QCD or in the …

The extraction of two-and three-body hadronic scattering amplitudes and the properties of
the low-lying hadronic resonances from the finite-volume energy levels in lattice QCD …

Strong three-body interactions above threshold govern the dynamics of many exotics and
conventional excited mesons and baryons. Three-body finite-volume energies calculated …

The dynamics of multikaon systems are of relevance for several areas of nuclear physics.
However, even the simplest systems, two and three kaons, are hard to prepare and study …

We perform a fit of the finite-volume QCD spectrum of three pions at maximal isospin to
constrain the three-body force. We use the unitarity-based relativistic three-particle …
