Abstract

摘要

The standard model of particle physics cannot explain origin of 5% visible matter (matter-antimatter asymmetry) and 25% dark matter. The Higgs Boson discovered in 2012 contains necessary ingredients and possible connections to address these mysteries. I will review the role of the Higgs Boson at early Universe, and then focus on Higgs portal new physics scenario which accommodates first order electroweak phase transition, baryogenesis, and WIMPy/asymmetric dark matter. This scenario provides rich signatures: possible Gamma-ray signal from Fermi-LAT Space Telescope, possible solution on Hubble constant tension, strong gravitational wave with space-based LISA detection, and future 100 TeV collider signatures. I will briefly discuss the interplay among these signatures in future experiments.
