Dual amplitudes for 6 pions with epsilon-tensor couplings

Дуальные амплитуды для 6 пионов с зпсилон-тенэорными свяэями

Summary

We construct a dual amplitude for 6 pions which contains the normal-parity trajectories ω-A2 in the three-body channels and ρ-f0 in the two-body ones. The leading trajectory is ghost free and has no parity doubling. Taking into account previous work, a complete solution of the construction of a 6-pion amplitude with all required physical properties in the tree approximation is now available.

Riassunto

Si costruisce un’ampiezza duale per 6 pioni che contiene le normali traiettorie di parità ω-A2 nei canali a tre corpi e ρ-f0 in quelli a due corpi. La traiettoria principale è priva di fantasmi e non ha raddoppio della parità. Tenendo conto di precedenti lavori si dispone ora di una soluzione completa della costruzione di un’ampiezza di 6 pioni con tutte le proprietà fisiche richieste nell’approssimazione ad albero.

Реэюме

Мы конструируем дуальную амплитуду для 6 пионов, которая содержит траектории с нормальной четностью ω-А2 в трех-частичных каналах и ρ-f0 в двух-частичных каналах. Главная траектория не имеет «духов» и удвоения четности. Принимая во внимание предыдушую работу, теперь имеется полное рещение по конструированию 6-пионной амплитуды со всеми требуемыми фиэическими свойствами.
