In this seminar, I will first discuss the prospects of a 125 GeV Higgs boson decaying into light LSP neutralino dark matter (DM) in MSSM and NMSSM in the context of collider searches and astrophysical experiments. I will discuss the possibility to derive clues on the nature of the DM through a study of complementarity between measurements at the future ILC and direct detection experiments. In the second part, I will revisit the SM non-resonant and resonant di-Higgs searches and briefly discuss the ramifications of varying the Higgs self-coupling on the optimized di-Higgs search strategies. I will conclude by discussing the contamination of existing di-Higgs search channels from SUSY processes.
