In this talk, I will present on the one hand information that we
already have on the properties of the potential
diphoton resonance at M~750 GeV, with a special focus on the flavor
structure. On the other hand, I will discuss how we can gain
insights, both directly on the resonance itself and it's relation
with the sector of electroweak symmetry breaking, as well as on the
physics producing/decaying it, via different precise measurements
at the LHC.
