The quark inside hadron
Abstract
Description
We study and solved Schwinger-Dayson equation for massive quarks in the quark model. Interaction potential is choose as sum oscillator and Coulomb terms. The calculation show us that negative energy of quark exist under $m_{o} \ll \Vo$ i.e. when mass quark is less that parameters of scale. Us are offered to use asymptotical behaviour at the solutions Schwinger-Dayson equation selection physical and non-physical conditions. The quark condensate under different values mass quarks are calculated. The scale parameters $\Vo$= 520 MeV.
