АНАЛИТИЧЕСКИЕ СВОЙСТВА ЗЛЕКТРОМАГНИТНЫХ АДРОННЫХ ФОРМФАКТОРОВ ВНЕ МАССОВОЙ ПОВЕРХНОСГИ И СВЯЗЬ МЕЖДУ ФОРМФАКТОРАМИ РАЗЛИЧНЫХ ЭЛЕКТРОМАГНИТНЫХ ВЕРШИН

摘要

Consequence of the analyticity of the electromag¬netic form factors in the invariant hadron masses and the unitarity condition has been investigated. In the frame¬ work of the Chew-Goldberger-Low-Nambu approach, a model of the electroproduction for the saturation of the sidewise dispersion relation has been choosen so, that besides the Born terms there was taken into account the exchange of mesons in the t-channel and the electric quadrupole of thetresonance in the channel.
