Pion and Kaon Masses and Pion Form Factors from Dynamical Chiral-Symmetry Breaking with Light Constituent Quarks
Michael D. Scadron, Frieder Kleefeld, George Rupp
Light constituent quark masses and the corresponding dynamical quark masses are determined by data, the quark-level linear sigma model, and infrared QCD. This allows to define effe…
Multichannel calculation of the very narrow and the very broad
George Rupp, Eef van Beveren
The narrow (2317) and broad (2300-2400) charmed scalar mesons and their radial excitations are described in a coupled-channel quark model that also repro…
Scalar and axial-vector mesons
Eef van Beveren, George Rupp
Nowadays, there exists an abundance of theoretical approaches towards the mesonic spectrum, ranging from confinement models of all kinds, i.e., glueballs, and quark-antiquark, mult…
Small Strange Quark Content of Protons
Michael D. Scadron, Frieder Kleefeld, George Rupp
The contribution of strange sea quarks to the proton mass and spin, as well as the related pion-nucleon sigma term, are briefly revisited, in the light of new experimental and latt…
D_{sJ}(2860) as the first radial excitation of the D_{s0}^*(2317)
Eef van Beveren, George Rupp
A coupled-channel model previously employed to describe the narrow (2317) and broad (2400) charmed scalar mesons is generalized so as to include all ground-state p…
The nature of , , and
E. van Beveren, D. V. Bugg, F. Kleefeld +1
Masses and widths of the four light scalar mesons , , (980) and (980) may be reproduced in a model where mesons scatter via a loop. A transition potentia…
Is the Y(4260) just a coupled-channel signal?
Eef van Beveren, George Rupp
The Ds-Ds*, D*-D*, and Ds*-Ds*, P-wave channels in the energy region of the Y(4260) charmonium structure are studied in a coupled-channel model applied to JPC=1-- c-cbar resonances…
Constituent Quark Masses and the Electroweak Standard Model
M. D. Scadron, R. Delbourgo, G. Rupp
Constituent quark masses can be determined quite well from experimental data in several ways and one can obtain fairly accurate values for all six . The strong quark-meson cou…
Pion Chiral Symmetry Breaking in the Quark-Level Linear Sigma Model and Chiral Perturbation Theory
Michael D. Scadron, Frieder Kleefeld, George Rupp
Chiral symmetry breaking (ChSB) is reviewed to some extent within the quark-level-linear-sigma-model (QLLM) theory and standard chiral perturbation theory (ChPT). It is shown, o…
