Yashar Aghababaie McGill I will discuss the compactification of a gauged 6D supergravity to 4 dimensions. The compactification to 4D shares many of the properties of realistic string compactifications, including four-dimensional space, 4D supersymmetry, chiral fermions and the appearance of moduli. I will discuss the construction of the 4D N=1 lagrangian, whose field content is that of an SO(3) x U(1) super Yang-Mills coupled to N=1 supergravity. One of the moduli fields is fixed through a Fayet-Iliopoulos term. I will then consider various corrections, including anomaly cancellation and the non-perturbative superpotential generated by the confining SO(3). Further corrections to the Kahler potential may provide a mechanism to fix the other (dilatonic) modulus, thus breaking SUSY. I will try to make the talk comprehensible to non-supersymmetric people.
