Prof. Hasenfratz studies strongly coupled systems that require nonperturbative methods. These include theories describing elementary interactions, like QCD and models for beyond Standard Model physics involving composite Higgs scenarios. They also include conformal or near-conformal systems, and systems that exhibit novel phases, like symmetric mass generation. Since these models are typically strongly coupled, she uses non-perturbative techniques, usually computational methods to numerically study these systems. Her work is of particular importance as the Large Hadron Collider continues to produce data and physicists can address phenomena at energies well beyond the presently understood energy range of the Standard Model.
