Andre Frankenthal joined the Princeton Physics department as a Dicke Fellow in September 2020. He works with the High-Energy Physics group searching for Beyond Standard Model physics using particle accelerators. His main research interests include searches for dark matter and experimental signatures of long-lived particles (LLPs) arising from proton-proton collisions with the Compact Muon Solenoid (CMS) experiment at CERN. To date there is ample evidence for the existence of dark matter but still quite limited knowledge about its composition. One promising collider signature to investigate is the decay of new LLPs, which are difficult to detect but could provide tantalizing evidence to the nature of dark matter that have evaded us so far.
Andre has also done R&D of new pixel silicon sensors and tracker prototypes for future upgrades of the CMS detector. On the software side, he is interested in techniques for improving computing performance to cope with the ever-growing datasets acquired by CERN experiments. Andre is also a member of PADME, a small fixed-target positron beam experiment in Frascati, Italy, to search for evidence of dark photons in positron-electron annihilations.
Andre received his Ph.D. from Cornell University under the supervision of Jim Alexander. His dissertation work focused on a search for inelastically-coupled dark matter with displaced final-state muons and missing transverse momentum.
