Summary

We propose a general procedure for constructing the scattering amplitudes of hadrons with external currents. These are obtained from a representation of theN-point function for hadrons and leptons, in the lowest order of the weak constant. We consider a model with external scalar mesons and vector currents only. Current conservation is not required. We study the form factor, electroproduction and Compton scattering finding good analytic properties for the amplitudes.

Riassunto

Si propone un metodo generale per costruire le ampiezze di scattering per adroni e correnti esterne. Tali ampiezze sono ottenute a partire da una rappresentazione della funzione adN punti per adroni e leptonic, all’ordine più basso nella costante debole. Si considera un modello con soli mesoni scalari esterni e correnti vettoriali. Non si richiede la conservazione della corrente. Si studiano il fattore di forma, l’elettroproduzione e lo scattering Compton, trovando buone proprietà analitiche per le ampiezze.

Реэуме

Мы предлагаем общую процедуру для конструирования амплитуд рассеяния адронов внещними токами. Амплитуды получаются иэ представленияN-точечных функций для адронов и лептонов в ниэщем порядке по слабой константе свяэи. Мы рассматриваем модель только с внещними скалярными меэонами и векторными токами. В модели не требуется сохранения тока. Мы исследуем форм-фактор, Электророждение и комптоновское рассеяние, причем, обнаруживаются хорощие аналитические свойства для амплитуд.
