"The beauty of the Higgs: measuring the most popular Higgs boson decay at the LHC"

Presented by Valerio Dao

Monday, April 3, 2023, 3:00 pm — Small Seminar Room, Bldg. 510

Abstract: In the Standard Model, the Higgs boson has the highest probability to decay to b-quarks (H->bb), yet this is one of the most challenging channels to study at the LHC. As such, it took six additional years after the initial Higgs-boson discovery to observe the H->bb decay for the first time. I will explain the importance of measuring the coupling of the Higgs boson to b-quarks and review the experimental techniques that led to the most precise H->bb measurement to date. I will present the state-of-the-art results and how they provide unique insight into possible anomalous interactions of the Higgs boson.

Finally, I will present future prospects highlighting the key role of the H->bb decay in investigations of the Higgs-boson self-coupling and developments to tackle the experimental challenges ahead. In particular, I will also discuss alternative pixel detector technologies for future colliders.
