The quark inside hadron

Abstract

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 $m_o\ll \text{Vo}$ 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 $\text{Vo}$= 520 MeV.
