Low lying states in the baryon spectrum
C. Helminen, D. O. Riska
The coupling to light mesons leads to large widths and shifts of the energy of the excited states in the baryon spectrum from the predictions of the constituent quark model with th…
The Gluon Exchange Interaction Between Constituent Quarks
C. Helminen, D. O. Riska
The interaction mediated by irreducible pion and gluon exchange between constituent quarks is calculated and shown to have a strong tensor component, which tends to cancel the pion…
Exchange Current Contributions to the Charge Radii of the Nucleons
C. Helminen
The exchange charge density operators that correspond to the Fermi-invariant decomposition of quark-quark interactions have been constructed. Their effect on the electromagnetic ch…
Baryon Magnetic Moments and Axial Coupling Constants with Relativistic and Exchange Current Effects
K. Dannbom, L. Ya. Glozman, C. Helminen +1
The large relativistic corrections to the constituent quark current operators improve the predictions for the axial couplings of the baryons, but worsen those for their magnetic mo…
