چکیده
It is shown that the binding effect that is associated with the short range part of the Goldstone boson exchange interaction between constituent quarks provides a good description of the πN σ-term.

The semi-leptonic decays of Σ ± offer a vehicle for observing charge symmetry-breaking. The effect is expected to be about 6%, enhanced due to the replacement of two u quarks by d quarks. We propose that present experimental data be improved to search for this effect.

Within the Chiral Quark Model we have calculated the effect of non-factorizable G 3 contribution to the BK parameter. When all diagrams are summed, a vanishing result is obtained.

It is argued that the mass spectrum of a baryon octet is linear, consistent with a Gell-Mann–Okubo type relation for the squared masses of the baryons obtained previously by Balázs and Nicolescu. The mass spectrum of a baryon decuplet is briefly discussed.
