Multiloop amplitudes in additive dual-resonance models

Многопетельные амплитуды в аддитивных дуальных резонансных моделях

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

A technique is developed by which general multiloop amplitudes in additive dual-resonance models can be calculated, with spurious states propagating internally in the loops, however. The result shows the same automorphic structure as has been found in the Veneziano model. The case of the Neveu-Schwarz model is considered in more detail.

Riassunto

Si sviluppa una tecnica per mezzo della quale si possono calcolare ampiezze «multiloop» tipo generale in modelli additivi di risonanze duali, con stati spuri propagantisi internamente alle anse. Il risultato mostra la stessa struttura automorfica che è stata trovata nel modello di Veneziano. Si considera più dettagliatamente il caso del modello di Neveu-Schwarz.

Резюме

Развивается техника, с помощью которой могут быть вычислены общие многопетельные амплитуды в аддитивных дуаляных резонансных модедлях, однако в этих петлях распространяьтся ложные состояния. Полученный результат обладает той же автоморфной структурой, как и следует из модели Венециано. Более подробно рассматривается случай модели Невэ-Шварца.
