Global Supersymmetry,step closer to realizing the second goal. However, since known “elementary” particles consist of both fermions (., .) and bosons (photons . color octet of gluons) their ultimate unification would require them either to be composites of some basic set of fermions which can be unified within a Lie gro

Field Theories with Global Supersymmetry, will then obtain certain constraints among the parameters of the bosonic and fermionic sectors of the theory and compare them with observations. The kind of field theories we are interested in will involve matter fields, which will be given by the chiral superfields and gauge fields, which in turn

As has been emphasized in Chapter 5, the tree level parameters must be fine tuned to an accuracy of 10. or so, to generate the mass ratio ../.. ? 10. in the SU(5) model. In other models, due to the presence to intermediate mass scales, the problem of fine tuning is not as s

Global Supersymmetry,up framework or that there must exist a new symmetry that transforms bosons to fermions. In this chapter, we begin discussion of this latter kind of symmetry [1], known as supersymmetry. Supersymmetry was invented in 1973 by Wess and Zumino [2] and earlier in a nonlinear realization by Volkov and Akulov [3].
