DISPERSION RELATIONS AND HIGH ENERGY LIMITS IN QUANTUM FIELD THEORY. PART II
Journal Article
·
· Progr. Theoret. Phys. (Kyoto)
The lower and upper bounds of the high energy limit of pion-nucleon forward scattering amplitudes are investigated. The former is studied using available experimental data, and it is found that at least one subtraction is necessary in the dispersion relations. The latter can be determined under requirement that the forward amplitude has no zero in the complex energy plane. Some discussions are given to the problem of the high-energy behavior in quantum field theories. (auth)
