Experimental sensitivity on HH and self-coupling is dominated by the big 3 channels (bbγγ, bbττ, bbbb) in Run2. However, various other decay modes provide significant sensitivity for future LHC runs due to detector and physics object improvement. This talk will review the current limitations of those channels and discuss the possibility of improvements.
The understanding of Higgs potential which is not measured experimentally well may provide hints of new physics that are not solved in the Universe. The observation of DiHiggs production and measurement of self-coupling is one of the next milestones of Higgs physics at the LHC. This seminar presents the latest DiHiggs and self-coupling measurement at the LHC Run2 data and future prospects at...
We discuss the impact of higher-order corrections on the Higgs di-photon decay in the inert doublet model. This model includes a scalar DM candidate, and it is known that the model can be tested indirectly by precisely measuring the Higgs di-photon decay rate and the Higgs self-coupling. We calculated the leading new-physics two-loop contributions to the Higgs di-photon decay rate for the...
