Peter Wittich

Peter Wittich is a Professor and Director of the Laboratory of Elementary Particle Physics at Cornell University's Department of Physics. His research focuses on experimental elementary particle physics, particularly exploring the fundamental building blocks of matter and the symmetries governing particle interactions. Wittich's work includes investigating the origin of mass, the Higgs Boson's role, and the matter-antimatter imbalance. He leads research at the CMS Experiment at the CERN LHC, emphasizing high-performance computing technologies like GPUs in particle physics reconstruction. Wittich is also involved in the CMS track trigger and addresses experimental challenges with increasing LHC energies and data rates.

Peter Wittich is a Professor of Physics at Cornell University, specializing in experimental particle physics. His research focuses on the detection and analysis of high-energy particle interactions, particularly within the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC). Wittich's work includes the observation of a new boson at 125 GeV, measurements of W and Z boson production cross sections, and studies of neutrino interactions. His contributions span particle-flow reconstruction, jet energy calibration, and the performance of muon and electron reconstruction systems. Wittich's research also involves the development of event generators and the validation of CMS detector performance in various collision environments.
