Summary
A way to account for the leading quantum corrections to the reggeon Green’s functions above the critical intercept is proposed with the results of Bronzan as a first nontrivial order. The results are in agreement with those recently obtained in a quantum formalism with appropriate boundary conditions. The relation to Gribov diagrams is briefly discussed.
Riassunto
Si propone un metodo per tener conto delle correzioni quantiche principali alle funzioni di Green per i reggeoni al di sopra dell’intercetta critica, con i risultati di Bronzan come primo ordine non banale. I risultati sono in accordo con quelli ottenuti recentemente in un formalismo quantico con appropriate condizioni al limite. Si discute brevemente la relazione con i diagrammi di Gribov.
Реэюме
Предлагается способ общяснения главных квантовых поправок к гриновским функциям реджеона выще критического пересечения. Полученные реэультаты согласуются с реэультатами, выведенными ранее в квантовом формалиэме с соответствуюшими граничными условиями. Вкратце обсуждается свяэь с диаграммами Грибова.
