Abstract
It is shown that a Froissart-Gribov-type partial-wave amplitude without signature can be defined for both two-body and multiparticle processes. Such an amplitude permits a Sommerfeld-Watson transformation, and its poles govern asymptotic behavior in the usual way, although unitarity properties of the amplitude are complicated. The relation to Toller amplitudes is discussed.Keywords
