Document Summary

The standard model re-written: today it is based on the electro-weak theory and on quantum chromodynamics, not final unified theory, total parameters in the standard model is no less then 27. Theoretical alternatives: most successful: grand unification theories (gut), pati-salam model, super-symmetry model, Introduced violet preons: can determine a certain proton disintegrated, experiments can only be conducted in a mine or at the bottom of the ocean because we are bombarded by neutrinos, neutrinos are emitted into the sun, gut. Idea of putting together quarks and electrons: disintegration between quarks and leptons. Instead of having electro-weak force, the colour force and the weak force become unified. Super-symmetry: for each fermion there is a super symmetric boson, particles we hope to see one day with the large hadron collider. Introduces work in many dimensions (11 dimensions: purpose to try to put quarks together with electrons.
