Strong interaction physics and the Padé approximation in quantum field theory
The application of Pade approximants to the scattering problem is considered. The following topics are covered: unitarity, crossing and analyticity problems; poles, Regge poles and unstable particles; practical convergence; strong interaction processes. It is concluded that the Pade approximation co...

| Sumario: | The application of Pade approximants to the scattering problem is considered. The following topics are covered: unitarity, crossing and analyticity problems; poles, Regge poles and unstable particles; practical convergence; strong interaction processes. It is concluded that the Pade approximation compares favourably with other approximation schemes for strong interaction physics. (86 refs). |
