The total ππ cross-section and the width of the forward diffraction peak at high energy

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We investigate the ππ scattering at low-momentum transfers, in order to understand diffraction scattering. High-energy effects at low-momentum transfers are automatically included by solving the integral equations with the short-range potential in addition to the long-range potential. Dynamical predictions are made on the magnitude of the total cross-section and the width of the forward diffraction peak, starting from a knowledge of the low-energy resonance parameters.

Riassunto

Si studia lo scattering ππ a piccoli momenti trasferiti allo scopo di capire lo scattering di diffrazione. Gli effetti di alta energia a piccoli momenti trasferiti sono automaticamente inclusi risolvendo le equazioni integrali col potenziale di corto raggio di azione in aggiunta al potenziale di lungo raggio d'azione. Si fanno predizioni dinamiche sulla grandezza della sezione d'urto totale e del picco di diffrazione in avanti, partendo dalla conoscenza dei parametri delle risonanze di bassa energia.
