Abstract:

The discovery of the Higgs boson at the Large Hadron Collider (LHC) marked a triumph for the Standard Model (SM) of particle physics. We know, however, that the SM is incomplete. We strongly believe that there is a deeper theory lying beneath, and the Higgs boson is a window toward the new physics beyond the Standard Model (BSM). Several new scalars have been predicted by the BSM models and they may be produced through the Higgs boson decays. Searching for these exotic decays of the Higgs boson is therefore a critical component of the physics program at the LHC. 
This talk will focus on the search for Higgs boson decays into a Z boson and a light hadronically decaying resonance with the ATLAS detector, and show the significant improvement in the sensitivity by employing neural networks.

Biography:

Dr. Chonghao Wu received PhD from University of Birmingham as a member of ATLAS collaboration. His research focuses on Higgs physics, new physics beyond the Standard Model, and searching for exotic Higgs decays at LHC using deep neural networks. Before joining ATLAS, he obtained a Master’s degree from University of Sheffield, and a Bachelor's degree in physics from Zhejiang University.
