Summary
We consider constraints on polarization due tos-channel unitarity. We find that polarizations may persist to all energies but that, if the amplitudes are exponentially peaked the spin flip peak must be at least half as wide as the nonflip peak.
Riassunto
Si considerano i vincoli sulla polarizzazione dovuti all'unitarietà del canales. Si trova che le polarizzazioni possono persistere a tutte le energie ma che, se le ampiezze hanno dei picchi esponenziali, il picco di spin-flip deve essere ampio almeno quanto la metà del picco senza flip.
Резюме
Мы рассматриваем ограничения на поляризацию, обусловленныеS-канальной унитарностью. Мы находим, что поляризации могут существовать при всех энергиях, но если амплитуды имеют экспоненциальные максимумы, то максимум с изменением ориентации спина должен составлять, по крайней мере, половину ширины максимума без изменения ориентации спина.

One can satisfy the constraint of unitarity for sufficiently small |f 0| and |g 0| so long as Ref 0>0. We have made this choice of phases for algebraic simplicity.
