要旨:
This paper is focused on the functional renormalization group applied to the
$T_5^6$ tensor model on the Abelian group $U(1)$ with closure constraint. In a
first time we derive the flow equations for the couplings and mass parameters
in a suitable truncation around the marginal interactions with respect to the
perturbative power counting. In a second time, we study the behavior around the
Gaussian fixed point, and show that the theory in non-asymptotically free.
Finally, we discuss the UV completion of the theory. We show the existence of
several non-trivial fixed points, study the behavior of the renormalization
group flow around them, and point out evidence in favor of an asymptotically
safe theory.
