Research Interests

Professor Orimoto’s research focuses on experimental particle physics, aiming to answer fundamental questions about the nature of our universe: Is it possible that there are extra-dimensions of space-time? What new particles or symmetries exist beyond the standard model of particle physics? What is the origin of mass for elementary particles?

Prof. Orimoto endeavors to answer such questions as a member of the Compact Muon Solenoid (CMS) Collaboration at the Large Hadron Collider (LHC) at CERN, in Geneva, Switzerland. The CMS Experiment is a general purpose particle detector experiment at the LHC, a 8 TeV proton-proton collider exploring a new high energy frontier. Prof. Orimoto’s work on CMS has centered around photons as a probe for discovery at the LHC. In particular, she is exploring photons as a decay channel for graviton excitations, which would be signature of extra-dimensions of space-time. She is also pursuing a search for supersymmetry (a hypothetical extension to the standard model of particle physics) in the photon final state. Finally, her work has culminated in the study of the Higgs boson in the two photon channel. In addition to her work on CMS physics analysis, she has played a leading role in the commissioning of the CMS electromagnetic calorimeter (ECAL), and she is currently interested in the operation and upgrade of the CMS ECAL.

Prior to joining the Northeastern faculty, Prof. Orimoto was a fellow at CERN (2009-2012) and the Robert A. Millikan fellow at the California Institute of Technology (2006-2009), as part of the CMS Collaboration. For her Ph.D. at the University of California, Berkeley, she studied charge-parity asymmetry with the Babar Experiment at the Stanford Linear Accelerator Center. She has also studied high resolution beam position monitors for a future linear collider.

Northeastern faculty conducting research with CERN

The European Organization for Nuclear Research, or CERN, has been making groundbreaking discoveries in nuclear and particle physics since its establishment in 1952. And there is a team of four Northeastern faculty who are involved with one of its projects.
