Evidence for BSM spin 0 and spin 2 resonances at LHC Possible Interpretations
Alain Le Yaouanc, François Richard
Nine statistically significant decay channels are observed in LHC data around a mass of 650 GeV. We interpret three of them as coming from a 20 GeV wide resonance observed in e+e-,…

X650 ZZ/WW/H125H95/A450Z/ -- , , narrow or wide resonance?
Alain Le Yaouanc, François Richard
At ICHEP 2024 CMS has published RUN2 results for ZZ->4 leptons and reached the conclusion that there is no evidence for a scalar resonance H650 decaying into ZZ, as was also conclu…

Triple Higgs couplings at LHC
Alain Le Yaouanc, François Richard
A global interpretation of several significant indications of scalar resonances observed at LHC is achieved using the Georgi Machacek model. Among many other consequences, one pred…
