In the cloudy-bag model, the value of the electric dipole amplitude of the photoproduction of neutral pions off protons at threshold connected with the additional contribution from the chiral symmetry breaking interaction is evaluated. If this additional contribution is included in the amplitude of the photoproduction of neutral pions off protons at threshold, the discrepancy between the LET predictions and the measured value of the electric dipole amplitude [Formula: see text] can be resolved for the values of quark masses and bag radii which are close to the generally used values.

Definition Of

We present the results of a computation of the surface tension on hadronic and gluonic droplets in finite temperature quenched lattice QCD. The surface free energy was obtained by integrating the average action along a path in coupling space corresponding to growing and melting a spherical droplet of a given radius. So far droplets of radius 4, 5 and 8 (in lattice units) have been considered. After discussing ambiguities in the definition of the surface tension due to a droplet’s finite size and thick interface, we compare our results with the Bag model study of Mardor and Svetitsky. Our calculations appear to confirm qualitatively their prediction of a negative surface tension for hadronic droplets with small radii. A similar result is found for gluonic droplets, in contrast however with the Bag model. We also compare our results with the recent lattice simulation of Kajantie, Karkkainen and Rummukainen.
