Estimation of the Properties of Quarks. I. Vector Quark?Quark Interaction

Abstract

From the sum rules for hadron scattering, the nucleon form factors, and the masses of the hadrons, the properties of quarks are estimated as: 2 Ge V Jc2 ;:; quark mass ;:; 30 Ge V Jc2, 0·1 fm ;:; range of the quark-quark interaction ;:; 0·25 fm. The hadrons are described by a relativistic independent quark model using the Dirac equation with a potential energy term for the effective interaction.
