Threshold amplitudes: Amplitude nullification via classical symmetries

  • 1. Department of Theoretical Physics II, University of Lodz, Pomorska 149/153, 90-236 Lodz (Poland)

Description

The Ward identities for amplitudes at the tree level are derived from the symmetries of the corresponding classical dynamical systems. The results are applied to some 2→n amplitudes
