Maximal supersymmetry and exceptional groups

Lars Brink (Institutionen för fundamental fysik, Elementarpartikelfysik)
Conference in Honour of Murray Gell-Mann's 80th Birthday on Quantum Mechanics, Elementary Particles, Quantum Cosmology and Complexity; Singapore; Singapore; 24 February 2010 through 26 February 2010 p. 262-272. (2010)
[Konferensbidrag, refereegranskat]

The article is a tribute to my old mentor, collaborator and friend Murray Gell-Mann. In it I describe work by Pierre Raniond, Sung-Soo Kim and myself where we describe the N-8 Supergravity in the light-cone formalism. We show how the Cremmer-Julia E7(7) non-linear symmetry is implemented and how the full supermultiplet is a representation of the E7(7) symmetry. I also show how the E7(7) symmetry is a key to understand the higher order couplings in the theory and is very useful when we discuss possible counterterms for this theory.
