Group-Theoretical Classification of BPS and Possibly Protected States in D=4 Conformal Supersymmetry
arXiv:1012.3685 · doi:10.1016/j.nuclphysb.2011.09.017
Abstract
We give explicitly the reduction of supersymmetries of the positive energy unitary irreducible representations of the N-extended D=4 conformal superalgebras su(2,2/N). Further we give the classification of BPS and possibly protected states.
