The Higgs and the expectation value of the number of elementary particles in a supersymmetric extensions of the standard model of high energy physics

Supersymmetry, colours and chirality are utilized to develop three minimally extended versions of the standard model. Based on these models, it is possible to predict that few new elementary particles are likely to be found experimentally at an energy scale which is very modestly above that of the electroweak. Connections to the 8064 massless states of Heterotic string theory are also discussed.
