  Several indications for neutral scalars are observed at the LHC. One of them,
a broad resonance peaked at about 650 GeV which we call H(650), was first
observed by an outsider combining published histograms from ATLAS and CMS on ZZ
-> 4 leptons searches, and this combination shows a local significance close to
4 s.d. Since then, CMS has reported two other indications at the same mass,
with similar local significances: H->WW->2leptons+neutrinos and
H(650)->bbh(125) where mbb~90 GeV and h(125)->gam gam. ATLAS has completed its
analysis of ZZ->4 leptons from which we infer an indication for H(650) with 3.5
s.d. significance. Combining these three results, one gets a global statistical
significance above 6 s.d. H(650) has a coupling to WW similar to h(125) and
therefore we argue that a sum rule (SR) required by unitarity for W+W-
scattering implies that there should be a compensating effect from a doubly
charged scalar H++, with a large coupling to W+W+. We therefore predict that
this mode should become visible through the vector boson fusion process
W+W+->H++, naturally provided by LHC. A recent indication for H++(450)->W+W+
from ATLAS allows a model independent interpretation of this result through the
SR constraint which gives BR(H++->W+W+)~10%, implying the occurrence of
additional decay modes H+W+ and H+H+ from one or several light H+ with masses
below mH++ - mW or MH++/2, that is mH+ < 370 GeV or 225 GeV. A similar analysis
is performed for H+(375)->ZW, indicated by ATLAS and CMS. Both channels suggest
a scalar field content similar to the Georgi Machacek model with triplets, at
variance with the models usually considered. Implications on precision
measurements are presented followed by a complete extraction of the GM
parameters. An alternate interpretation of the 650 GeV resonance as a tensor is
also briefly discussed. Implications for precision measurements are presented.
