Wave functions of octet baryons

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The leading twist baryonic wave function ϕ(x 1,x 2,x 3) describes the distribution of three quarks inside the baryon in the longitudinal momentum fractions 0≦x i ≦1 atP z →∞. The properties of these wave functions for the baryons entering the nucleon octet are investigated using the QCD sum rules. The high asymmetry in the distribution of the baryon momentum between three quarks is found for all members of the octet. The properties of theSU(3)-symmetry breaking effects in baryonic wave functions are elucidated. The model wave functions are proposed which fulfil the sum rules requirements. The asymptotic behaviour of various baryon form factors (which can be measured ine + e −→\(\bar {\rm B}\) B) is found out.
