High Energy Physics Seminar - Suyog Shrestha (The Ohio State University/ATLAS) Higgs Boson as a Probe in the Search for Physics Beyond the Standard Model

After the discovery of the Higgs boson in 2012, several of its properties have been measured which have been found to be consistent with the Standard Model expectations. Some of its properties such as self-coupling, coupling to lighter quarks, etc. have not been measured yet. Additionally, the Higgs boson itself can be used as a probe in the search for physics beyond the Standard Model through the observation of its pair production (addressing self-coupling) or rare decay modes (addressing coupling to lighter fermions). In this talk I will summarize the recent results in the search for pair production and rare decay of the Higgs boson using the ATLAS detector, and also discuss the prospects for High Luminosity LHC program.
