On amplitude zeros at threshold
E. N. Argyres, C. G. Papadopoulos, R. Kleiss
The occurrence of zeros of 2 to n amplitudes at threshold in scalar theories is studied. We find a differential equation for the scalar potential, which incorporates all known case…

Multiscalar production amplitudes beyond threshold
E. N. Argyres, C. G. Papadopoulos, R. Kleiss
We present exact tree-order amplitudes for , for final states containing one or two particles with non-zero three-momentum, for various interaction potentials. We show…
