DESCRIPTION:In this talk\, I will present a sextic tensor model with inter
 action terms given by all $O(N)^3$-invariant bubble diagrams. I will const
 ruct the large-$N$ limit of this model and show that novel classes of domi
 nant tensor graphs emerge\, beyond those present in the $U(N)^3$ case. I w
 ill then present the computation of renormalization group fixed points for
  the higher-dimensional tensor field theory generalization of this model\,
  considering both short-range and long-range propagators\, and using a dia
 grammatic expansion of the vertex function. \nThis work is joint with T. 
 Krajewski\, T. Muller\, and A. Tanasa\, based on arXiv:2510.19646 [hep-th]
