Almost optimality of an axiomatic bound for pi$^{0}$pi$^{0}$ scattering

The authors produce a pi /sup 0/ pi /sup 0/ to pi /sup 0/ pi /sup 0/ amplitude F(s, t) which fulfils all the analyticity, crossing and unitarity conditions used in the derivation of rigorous absolute bounds, and such that F(/sup 4///sub 3/,/sup 4///sub 3/)=2.62. When compared to the axiomatic result...

description The authors produce a pi /sup 0/ pi /sup 0/ to pi /sup 0/ pi /sup 0/ amplitude F(s, t) which fulfils all the analyticity, crossing and unitarity conditions used in the derivation of rigorous absolute bounds, and such that F(/sup 4///sub 3/,/sup 4///sub 3/)=2.62. When compared to the axiomatic result of Lopez and Mennessier (1977), -8.2<F(/sup 4///sub 3/,/sup 4///sub 3/)<2.75, this example shows that no further significant improvement of the upper bound can be expected.
