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 …

Quantum chromodynamics (QCD), the generally accepted theory for strong interactions,
describes the interactions between quarks and gluons. The strongly interacting particles that …

Observations of exotic structures in the J/ψ p channel, which we refer to as charmonium-
pentaquark states, in Λ b 0→ J/ψ Kp decays are presented. The data sample corresponds to …

A bstract We determine the light baryon spectrum on ensembles generated by the
Coordinated Lattice Simulations (CLS) effort, employing N f= 2+ 1 flavours of non …

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 …

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 …

The data sample of Λ b 0→ J/ψ p K-decays acquired with the LHCb detector from 7 and 8
TeV pp collisions, corresponding to an integrated luminosity of 3 fb-1, is inspected for the …

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 …

The last two decades have witnessed the discovery of a myriad of new and unexpected
hadrons. The future holds more surprises for us, thanks to new-generation experiments …

Discovered in 1963, the Roper resonance appears to be an exact copy of the proton except
that its mass is 50% greater and it is unstable. These features of the Roper have been very …
