摘要:

The instanton-induced determinantal ’t Hooft interaction is built into a three-flavor linear sigma model which is considered in the OZI-rule-respecting basis{(s¯s),1/&sqrt2;(u¯u+d¯d)}.The mixing of the strange and non-strange quarkonia, which emerges in the presence of instantons, is shown to be ideal thus leading to the formation of an octet-flavor state. ©2001 American Institute of Physics.

摘要:

We study thesands¯lowQ2non-perturbative distributions in protons in the framework of the Meson Cloud Model. From a comparison of model predictions to a recent global fit from Deep Inelastic Scattering data on thesands¯quark distribution functions in protons, we extract qualitative information on the strange quark distribution functions in hyperons and kaons. ©2001 American Institute of Physics.
