We review selected theoretical results for diphoton production at the LHC concerning Standard Model studies and new physics searches, at the light of the recent 750 GeV excess.

We discuss the equation of state in the confining regime of SU(N) Yang-Mills theories in (2+1) and (3+1) dimensions. We show that the results are described very well by a gas of massive, non-interacting glueballs, provided one assumes that, in addition to the known particles lighter than the two-particle threshold, the theory features a physical spectrum described by an...

Vectorlike Confinement is one of the simplest and most plausible scenarios for new physics beyond the SM, obtained by adding new fermions in vectorlike representations of the SM gauge group, with a mass scale possibly accessible at the LHC. These fermions are charged under a new gauge strong interaction that confines without breaking the SM gauge symmetry. The new physics is not related to the...

We will present a determination of the topological properties of QCD for temperatures above the deconfinement, up to T~600MeV. Numerical results obtained by means of Lattice QCD simulations will be compared with the prediction of instanton gas calculations. Finally, the implications of these results for the cosmological bounds on the axion mass will be discussed.
