Summary
It is shown that phase dispersion relations and certain general assumptions imply both logarithmic andO(1/q 2) departures from Bjorken scaling in deep inelastic scattering, in analogy with QCD. Implications on the Harari counterargument on the moment test for the structure functions are discussed.
Riassunto
Si mostra che le relazioni di dispersione di fase e certe ipotesi generali implicano sia l'allontanamento logaritmico che quelloO(1/q 2) dalla variazione di scala di Bjorken nello scattering inelastico profondo in analogia con la QCD. Se ne discutono le implicazioni riguardo alla replica di Harari sulla prova dei momenti per le funzioni di struttura.
Резюме
Показывается, что фазовые дисперсионные соотношения и некоторые общие предположения подразумевают логарифмическое иO(1/q 2) отклонения от подобия Бьёркена в глубоко неупругом рассеянии, по аналогии с квантовой хромодинамикой. Обсуждаются следствия, касающиеся контр-аргумента Харари об импульсной проверке для структурных функций.
