In this talk I will review the experimental results about hints of significant deviation from SM predictions in the diphoton mass spectrum. I will also discuss the interpretation of this putative signal in relation to other searches for new phenomena carried out at the LHC. After this phenomenological characterization, I will motivate how new strong interactions at the TeV scale are a leading candidate to explain the putative signal and I will discuss a few examples of Goldstone bosons and related degrees of freedom that can account for the putative signal. Furthermore I will discuss key observations to be carried out in the future to test the nature of the theory behind the putative signal, *e.g.* the CP parity of the new states and their pair production.
