A summary of supersymmetry and supergravity

Abstract

Supersymmetry (SUSY) SUSY is an attractive concept whose basic feature is a transformation which relates bosons to fermions and vice-versa [1-13]. Its promotion to a gauge symmetry has resulted in an elegant field theory called supergravity (SUGRASUGRA String duality!N=1 SUGRA String duality!N=2 SUGRA String duality!N=8 SUGRA ) [14-20]. One of its most significant features is that the presence of local SUSY naturally implies spacetime to be curved. Hence, gravity must necessarily be present. © 2010 Springer-Verlag Berlin Heidelberg.
