Level order of quark systems: The puzzle of the Roper resonance, and related questions
Jean-Marc Richard
The problem of ordering of radial vs.\ orbital excitations is reviewed. It is shown that the current quark models cannot explain the location of the Roper resonance which is slight…
Stability of multiquarks in an improved flip-flop model of confinement
J. Vijande, A. Valcarce, J. -M. Richard
We review some recent studies on the string model of confinement inspired by the strong-coupling regime of QCD and its application to exotic multiquark configurations. This include…
Stability of multiquarks in a simple string model
J. Vijande, A. Valcarce, J. -M. Richard
A simple string model inspired by the strong-coupling regime of Quantum ChromoDynamics is used as a potential for studying the spectrum of multiquark systems with two quarks and tw…
Light and heavy multiquark spectroscopy
J. M. Richard
The dynamics of multiquark binding is revisited in the light of the recent experimental results. It is emphasized that some configurations mixing light and heavy flavours are among…
Scalar meson exchange and the baryon spectra
P. Stassart, Fl. Stancu, J. -M. Richard
We explore the role of a scalar meson exchange interaction between quarks in a semirelativistic constituent quark model where the quarks are subject to a linear confinement. We sea…
Heavy-Flavour Pentaquarks in a Chiral Constituent Quark Model
M. Genovese, J. -M. Richard, FL. Stancu +1
Within the chiral constituent quark model of Glozman and Riska, we discuss the stability of heavy pentaquarks, i.e. hadrons containing four light quarks and a heavy antiquark. The…
Isospin Splittings of Baryons
K. Varga, M. Genovese, J. -M. Richard +1
We discuss the isospin-breaking mass differences among baryons, with particular attention in the charm sector to the , , and splittings…
Search for Flavoured Multiquarks in a Simple Bag Model
S. Zouzou, J. -M. Richard
We use a bag model to study flavoured mesonic and baryonic states, where one heavy quark is associated with light quarks or antiquarks,…
