One of the deepest scientific mysteries in the 21 century is to understand the nature of dark matter which contributes a large component of the mass-energy of the universe. The leading hypothesis suggests that most dark matter is in the form of stable, electrically neutral, massive particles which interact with the Standard Model particles at a weak scale or below. The discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 opens a new window to search for new particles of this kind.
In this presentation, I will describe alternative probes of dark matter using the Higgs Boson with the ATLAS detector at the LHC. I'll demonstrate how a boosted (high momentum) pair of bottom quarks decayed from the Higgs boson can broaden the search for dark matter. I'll show the state-of-the-art techniques to reconstruct boosted Higgs Boson, and discuss latest search results as well as their implications. Finally, I'll present new ideas to improve the Higgs identification which can push the frontier of Beyond the Standard Model physics searches at the LHC.
