Derivation and implications of rigorous absolute bounds for pi pi partial waves up to 1 GeV

Mostrar otras versiones (1)

Generalized dispersion relations and axiomatic results are used to derive absolute upper bounds for the pi pi partial waves in a complex energy domain containing the physical region up to 1 GeV. As applications, a new lower bound for the pi /sup 0/ pi /sup 0/ S-wave scattering length is given and so...

description Generalized dispersion relations and axiomatic results are used to derive absolute upper bounds for the pi pi partial waves in a complex energy domain containing the physical region up to 1 GeV. As applications, a new lower bound for the pi /sup 0/ pi /sup 0/ S-wave scattering length is given and some ambiguities in the connection between resonances and second sheet poles are removed. (11 refs).
