  We describe some of the future measurements to be performed by the CMS, TOTEM
and ATLAS collaborations on hard diffraction in order to understand better the
structure of the Pomeron. We also describe the prospects concerning the search
for quartic $\gamma \gamma \gamma \gamma$ anomalous couplings and discuss a
possible interpretation for the existence of a new particle decaying into two
photons at a mass of about 750 GeV.
