# Standard model fermions and K (E10)

@article{Kleinschmidt2015StandardMF, title={Standard model fermions and K (E10)}, author={Axel Kleinschmidt and Hermann Nicolai}, journal={Physics Letters B}, year={2015}, volume={747}, pages={251-254} }

Abstract In recent work [1] it was shown how to rectify Gell-Mann's proposal for identifying the 48 quarks and leptons of the Standard Model with the 48 spin- 1 2 fermions of maximal SO(8) gauged supergravity remaining after the removal of eight Goldstinos, by deforming the residual U(1) symmetry at the SU(3) × U(1) stationary point of N = 8 supergravity, so as to also achieve agreement of the electric charge assignments. In this Letter we show that the required deformation, while not in SU(8… Expand
