Figure 10 illustrates the EGM effect which lowers by a factor 700 the
threshold for the production of the lightest superparticle.
The mathematical formalism used to obtain the results shown in Figures
9 and 10 is a system of three differential non-linear equations (shown in Figure
11) describing how the gauge couplings
i , j (with i = 1, 2, 3; and J = 1, 2, 3 but i j),
vary with ‘’, the basic parameter which depends on the energy of a given
elementary process.
Figure 11.
During more than ten years (from 1979 to 1991), no one had realized
that the energy threshold for the existence of the Superworld was strongly
dependent on the ‘running’ of the masses.
