The UChicago ATLAS group pursues exciting physics using groundbreaking techniques. Our graduate students and postdoctoral researchers earn international recognition for leading these high-impact analyses.
Our diverse physics efforts capitalize on our unique strengths in ATLAS instrumentation, Monte Carlo simulation, and software. We play active roles understanding the recorded data, triggers, and physics objects used in analysis. This includes jets, missing transverse momentum, flavor tagging, and tracking.
We perform uncharted measurements of the Standard Model and foundational properties of the Higgs boson. Measuring the Higgs self-coupling is central for elucidating electroweak symmetry breaking.
We have led precise measurements of vector bosons with jets, dijet cross-sections, unique W production emitted from a high momentum quark, and W+/W- charge asymmetry as tests of parton distributions.
Using the Higgs boson and hadronic jets to probe new physics is a focal point of our searches for exotic resonances, dark matter, dark photons, and dynamics that could modify the Higgs self-coupling.
We develop novel techniques for tracking inside jets, tagging boosted objects such as top quarks, gauge and Higgs bosons. We also pioneer displaced leptons to search for long-lived supersymmetric particles.
Why is it the only known force that confines? How does the non-perturbative evolve into perturbative regimes at the highest energies? What measurements can improve precision modeling for new physics searches?
How do boosted jets modify electroweak gauge boson dynamics? What happens when photons collide at LHC energies? How can precise Standard Model tests be sensitive to new physics?
Does the Higgs interact with itself? What is the shape of the Higgs potential? How often does it decay invisibly to neutrinos or dark matter? Could it open windows on the mysterious matter-antimatter asymmetry?
How can we use the Higgs boson to probe new physics? Could the LHC produce dark matter and its mediators to study in the laboratory? What signatures of unified forces or dark sectors could we reveal?
How can we discover long-lived supersymmetric states? How can we exploit hadronic signatures to open new sensitivity? What techniques could reveal challenging corners of search space beyond the lamppost?
