GUTs versus Susy GUTs,ays, and very justifiably so. They do not simply contain the successful electroweak and strong interactions (QCD) theories, but they lead to numerous qualitative and quantitative results, most of them impossible to be derived in the absence of grand unification..

Grand Unification in Extended Supergravity,particle interactions and extended super-gravities. My principal collaborators in this endeavour have been Mary K. Gaillard and Bruno Zumino., and as between us we have already written several reviews. of our approach, this paper is intended to emphasize recent developments at the expense of older results.

Supersymmetry Breaking Through a Cosmological Constant,ngian which is invariant under N = 1 gauged supersymmetry transformations. Expanding this Lagrangian around flat space leads to an explicit breaking of supersymmetry, This breaking scheme depends on one parameter only and it turns out to be renormalizable.

规章

Recent Developments in the Group-Manifold Approach,The “group-manifold” scheme for the formulation of supersym-metric theories, its goals and advantages have already been reviewed in other conferences: in particular we refer the reader to Ref. 1 and to all the papers quoted therein.

Towards Unification with Just Fundamental Fermions,Fermions are an essential constituent in Nature. Could they be the only fundamental constituents? For instance, could all other particles required by low energy phenomenology, e.g., gauge bosons and Higgs scalars, be bound states of just fermions? Here I show how this appealing suggestion might be realized.

Axions,Considering a coloured fermion f. (a = 1,2,3) coupled to QCD, we first write the usual Lagrangian, using standard notations:
