Professor Baker’s research is in experimental particle physics: The energy frontier at the Large Hadron Collider in the ATLAS collaboration and precision studies at sub-eV energies. Current topics include quantum information science in HEP, electroweak symmetry breaking, and beyond the standard model physics searches.
Experimental particle physics research in the ATLAS collaboration at the LHC.
Built the detectors and carried out ML analysis in the Higgs boson discovery.
Originated ATLAS analysis search for Dark Sector (BSM) phenomena in exotic decays of the Higgs boson to four leptons.
Co-pioneered LHC research Quantum Information Science (quantum entanglement, entanglement entropy) in proton-proton collisions.
