Description
Realistic E6 GUTs were proposed in recent years with nice and peculiar features like the existence of a dark matter candidate and/or a correct Yukawa structure. The price to pay in such models is the use of large representations of the E6 group, which make the theory UV non-free with a Landau pole less than one order of magnitude above the GUT scale. I will present in this talk an E6 model with only 27 and 78 dimensional representations which are potentially realistic and which may be well behaved up to the Planck scale. The work is in progress in collaboration with K. Babu and Vasja Susič.
