This talk will present the study on the BSM resonance search in H->SS/Sh with 2HDM+S model at the LHC. Based on ATLAS/CMS pubic results, we observed a local (global) excess of 5.1 sigma (4.8 sigma) around 151.5 GeV in di-photon/z/gamma final states with associated leptons, di-jets, bottom quarks and missing energy. Related to this excess, the “multi-lepton anomalies” accumulated by the analysis of LHC data will be addressed. We will also propose the further searches about this at the LHC. Finally, the impact of those to BSM search in future e+e- collider will be briefly discussed as well. Tecent Meeting: https://meeting.tencent.com/dm/gICKeFxR0RLC Meeting ID：605 599 472
