PhD Project
| Preliminary title: Investigation of Higgs properties in the di-tau channel at FCC-ee and CMS |
| Duration: March 2024 – July 2027 (expected) |
| Summary: I study how the Higgs bosondecays into pairs of τ leptons. I use data from the CMS experiment at the Large Hadron Collider (LHC) and prepare the physics case for the Future Circular Collider (FCC-ee), a proposed electron–positron collider at CERN. A particular question is whether the Higgs boson treats matter and antimatter symmetrically (CP violation). |
