The Higgs boson, supersymmetry and dark matter: Relations and Perspectives

The discovery of a light Higgs boson at the LHC opens a broad program of studies and measurements to understand the role of this particle in connection with New Physics and Cosmology. Supersymmetry is the best motivated and most thoroughly formulated and investigated model of New Physics which predicts a light Higgs boson and can explain dark matter. This paper discusses how the study of the Higgs boson connects with the search for supersymmetry and for dark matter at the LHC and at a future e+e− collider and with dedicated underground dark matter experiments. The Higgs boson discovery at LHC starts an exciting program to understand the role of this particle in connection with New Physics and Cosmology. Supersymmetry is the best motivated and thoroughly formulated model of New Physics predicting a light Higgs and able to explain dark matter. This paper connects the study of the Higgs boson with the search for supersymmetry and dark matter at colliders and underground experiments.
