Green’s function techniques and dual fermion loops

Техника гриновских функций и дуальные фермионные петли

Summary

Using some recent techniques of Mandelstam for the Neveu-Schwarz-Ramond model we calculate the momentum-dependent contribution to the one-loop planar and nonplanar amplitudes for both fermions and mesons in a unified way and thus obtain a better understanding of previous results, together with some new results on fermion loops.

Riassunto

Per mezzo di alcune recenti tecniche di Mandelstam relative al modello di Neveu-Schwarz-Ramond si calcola in modo unificato il contributo dipendente dall’impulso alle ampiezze a un solo lobo planari e non planari sia per i fermioni che per i mesoni. Si ottiene quindi una comprensione migliore dei risultati precedenti insieme a qualche risultato nuovo sui lobi dei fermioni.

Реэюме

Испольэуя недавно предложенную технику Манделстама для модели Невз-Щварца-Рамонда, мы единым обраэом вычисляем эависяший от импульса вклад в однопетельные плоские и неплоские амплитуды для фермионов и меэонов. Это поэволяет лучще понять предыдушие реэультаты и получить некоторые новые реэультаты для фермионных петель.
