The Higgs boson, discovered in 2012 at the Large Hadron Collider (LHC), confirmed a key piece of the Standard Model, the theory that describes the basic particles of matter and how they interact. Major questions remain unanswered.

What they work on
- Search ATLAS data from the Large Hadron Collider for new Higgs-like scalar particles that decay into two bottom quarks and two W bosons, in final states with one or two leptons, a decay channel ATLAS has not yet studied.
- Design trigger strategies, the real-time rules that decide which collisions are recorded, and use kinematic fitting to improve signal selection and event reconstruction in the bbWW search.
- Develop multivariate classification frameworks informed by kinematic fits to separate possible new-particle signals from Standard Model background, using Monte Carlo simulations of signal topologies.
- Contribute to the calibration of b-jet triggers, which pick out collisions containing bottom-quark jets, to support a wide range of ATLAS analyses.
More about the research
Why does the universe contain more matter than antimatter? Why do neutrinos have mass? What is dark matter? Is the known Higgs the only one, or part of a larger family? Many extensions of the Standard Model predict additional Higgs-like particles, called scalars, that could mix with the known Higgs.
Why it matters
The project tests whether the Higgs boson belongs to a larger family of particles. This is a basic science question tied to dark matter, neutrino mass and why matter outnumbers antimatter. Finding new scalars, or ruling them out more strictly, would narrow which theories beyond the Standard Model remain possible. Its b-jet trigger calibration also supports many other ATLAS analyses.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
