Olcyr de Lima Sumensari

Olcyr Sumensari is a CNRS Researcher affiliated with IJCLab (Laboratoire de Physique des 2 Infinis “Irène Joliot-Curie”, in Orsay, France), working in theoretical high-energy physics. His research centers on flavor physics—phenomena involving different “flavors” of quarks and leptons and their potential to reveal physics beyond the Standard Model. He investigates new-physics scenarios using both effective field theory and explicit models, such as those with extended scalar sectors or leptoquarks. His work examines rare processes, lepton-flavor violation, and possible connections to dark matter and other extensions of fundamental interactions.

By developing precise theoretical predictions testable in current and future experiments, he works at the interface of theory and phenomenology. Flavor physics is one of the most sensitive probes of new physics, where even small deviations from Standard Model expectations may indicate new particles or interactions. Through studies of heavy flavor, lepton flavor, and rare decays, his research identifies promising avenues for discovery in upcoming experimental programs.
