Chatterjee receives Young Researcher Prize
Rajdeep Mohan Chatterjee received the 2022 Young Researcher Prize from the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) in Switzerland.
Chatterjee was cited “for his crucial and sustained contributions to the electron/photon reconstruction in the ECAL, the analysis of decay channel H-> gg, the precise determination of the mass of the Higgs boson, and test beam studies of the HGCAL.”
The Standard Model predicts the existence of the Higgs boson as well as all its properties, but not the mass. Chatterjee's research made a measurement of the Higgs boson mass that is the most precise (~0.1%) to date. He led a team in calibrating the energies of electrons and photons with enhanced precision and contributed to the development of a novel machine learning algorithm for optimal energy reconstruction of electrons and photons which significantly improves their energy resolution. He has also been involved in research and development for the High Granularity Calorimeter for the LHC, focusing on the commissioning, operations of the prototype detector in beam tests and the application of machine learning methods in the event reconstruction.
Chatterjee works with Professor Roger Rusack's research group at the CMS experiment.
