Description
We discuss the possibility that QCD is not asymptotically free and develops instead an interactive UV fixed point. This can happen if the Standard Model is extended by a set of $N_F$ vector-like fermions that transform non-trivially under $SU(3)_c$, with Yukawa-type interactions mediated by a $N_F\times N_F$ matrix scalar field. We point out that the $750$ GeV diphoton excess can be explained within such a framework.
