  This paper intends to collect available data on searches for scalar
resonances at LHC. It is suggested that, in the absence of SUSY, the most
compelling picture is the composite framework, with the idea that the lightest
particles are composite scalars of the pseudo-Nambu-Goldstone type, emerging
from a broken symmetry at a higher scale, the h(125) boson being one of them.
Searches in two-photons, Z-photon, ZZ into 4 leptons, top, h and W pairs are
reviewed. A recent search based on lepton tagging from a spectator W/Z is also
discussed. Aside from the already well-known scalar observed by CMS and LEP2 at
96 GeV, I discuss the evidence and the interpretation for a possible resonance
observed in ZZ around 700 GeV by CMS and ATLAS and some evidence for a CP-odd
scalar at ~400 GeV. Future searches at HL-LHC and at $e^+e^-$ colliders are
briefly sketched.
