Episode notes

This chapter discusses the challenges and advancements in particle physics, focusing on the standard model and the quest for deeper theoretical understanding. It highlights the complexities of particle behavior, specifically the Higgs boson and the implications of its unexpected mass. The conversation reflects on public perceptions of discovery rates in the field, emphasizing the intricate nature of physics and the significant progress made in understanding fundamental particles.

As an experimental facility, the Large Hadron Collider at CERN in Geneva has been extraordinarily successful, discovering the Higgs boson and measuring multiple features of particle-physics interactions at unprecedented energies. But to theorists, the results have been somewhat frustrating, as we were hoping to find brand-new phenomena beyond the Standard Model. There is nothing to do but to keep looking, recognizing that we have to choose our methods judiciously. I talk with theoretical physicist Cari Cesarotti about what experimental results the modern particle physicist most looks forward to, and how we might eventually get there, especially through the prospect of a muon collider.

Cari Cesarotti received her Ph.D. in physics from Harvard University. She is currently a postdoctoral fellow at MIT. Her research is on particle phenomenology theory, with an eye toward experimental searches. Among her awards are the Sakurai Dissertation Award in Theoretical Physics from the American Physical Society and the Young Scientist Award at the 14th International Conference on the Identification of Dark Matter.
