Epsilon production in a geometrical approach

In a previous paper ε production was studied, by making used of dual properties, and it was qualitatively shown that pion exchange dominates near the forward direction and there is a small exchange with the A₁ quantum numbers. This is confirmed by the polarization data, since it clearly shows that t...

Sumario:In a previous paper ε production was studied, by making used of dual properties, and it was qualitatively shown that pion exchange dominates near the forward direction and there is a small exchange with the A₁ quantum numbers. This is confirmed by the polarization data, since it clearly shows that two independent amplitudes are essential in this reaction. Duality also provides a guidance for the position of the zeros of the imaginary parts of these amphtudes. In this note we shall take over this problem again and quantitatively show that the dual predictions are in agreement with the experimental data.
