The quark model was formulated in 1964 to classify mesons as bound states made of a
quark–antiquark pair, and baryons as bound states made of three quarks. For a long time all …

A large number of experimental discoveries especially in the heavy quarkonium sector that
did not meet the expectations of the until then very successful quark model led to a …

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 …

We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

The two-body decay rate of a weakly decaying particle (such as the kaon) is shown to be
proportional to the square of a well-defined transition matrix element in finite volume …

We generalize the Lellouch-Lüscher formula, relating weak matrix elements in finite and
infinite volumes, to the case of multiple strongly coupled decay channels into two scalar …

We determine elastic and coupled-channel amplitudes for isospin-1 meson-meson
scattering in P wave, by calculating correlation functions using lattice QCD with light quark …

We present the first study of baryon-baryon interactions in the continuum limit of lattice QCD,
finding unexpectedly large lattice artifacts. Specifically, we determine the binding energy of …

A lattice QCD computation of the coupled channel π Σ–K¯ N scattering amplitudes in the Λ
(1405) region is detailed. Results are obtained using a single ensemble of gauge field …
