News Academy of Engineering Sciences A.M. Prokhorov Annotation << Back Electrostatic calculation of the mass difference between the neutron and proton (model of strongly quarks) A.A. Sobko S.A. Garelina All textbooks and monographs noted that the difference between neutron and proton masses caused by electrostatic (Coulomb) interaction, but the calculation of this interaction in the literature. In the present study, in contrast to [3], in which the quarks inside the nucleon treated as free particles, considered strong (gluon) interaction, which does not allow quarks leave nucleon. On the basis of the quark model of the nucleon Monte Carlo calculated Coulomb assumption that if the quark is in the area in which, where defines the beginning of the area in which the gluon interactions included the probability of finding a quark there is less than one. Proposed, more realistic model of the quarks in the nucleon, yielded agreement between the calculated and experimental value of the mass difference between the neutron and the proton, and to assess the area in which significant gluon interactions.
