Summary
A regularization scheme for QCD proposed by Migdal for two-point functions is extended to three-point functions. We consider first some general implications of the analytic structure of the three-point function. We then discuss extensively the hadronization of meson and baryons structure functions and form factors, in particular their behaviour forx→1 and |q 2|→∞, respectively.
Riassunto
Si estende lo schema di regolazione per la QCD, proposto da Migdal per funzioni a due punti, a funzioni a tre punti. Si considerano prima alcune implicazioni generali della struttura analitica della funzione a tre punti. Si discute quindi in maniera estensiva l'adronizzazione delle funzioni di struttura barionica e mesonica e dei fattori di forma, in particolare il loro comportamento perx→1 e |q 2|→∞, rispettivamente.
Резуме
Схема регуляризации для квантовой хромодинамики, предложенная Мигдалом для двухточечных функций обобщается на случай трехточечных функций. Мы рассматриваем общие следствия аналитической структуры трехточечной функции. Затем мы обсууждаем адронизацию мезонных и барионных структурных функций и форм-факторов, в частности, их поведение соответственно приx→1 и |q 2|→∞.
