Abstract

A previous supersymmetric preon scenario for the first generation particles is extended to include all three generations and the dark sector. The scenario is reformulated as a double field theory (DFT) in 4+4 dimensions. It is proposed that DFT preons are the pointlike limit of string theory below the string scale ~ 10^(18) GeV. The need for extra string theory dimensions is argued to reduce from six to two.
