Elementary Particle Physics Group
Jonathan Bagger is continuing his studies of supersymmetry and supergravity. In addition to his more formal work on the interconnection between string theory and field theory he has also been investigating the phenomenology of supersymmetry at high energy colliders.

Marc Kamionkowski works in cosmology, astrophysics, and elementary-particle theory. His main research interests are on particle dark matter, inflation and the cosmic microwave background, and cosmic acceleration. However, he has also worked on neutrino and nuclear physics and astrophysics, cosmic large-scale structure and galaxy formation, gravitational waves, gravitational lensing, cosmic phase transitions, alternative-gravity theories, the epoch of reionization, and a bit in stellar and high-energy astrophysics.

David Kaplan's main research interest is on physics beyond the standard model of particle physics.  He constructs models which may explain the existence and the size of the electroweak scale (and therefore the masses of nearly all fundamental particles) and analyzes their implications for collider and other experiments.  He uses effective field theory techniques and applies them to models with supersymmetry, extra dimensions or other symmetry extensions to the current framework.  He is also interested in the applications of these techniques to cosmological models and in general particle physics implications for cosmology and vice-versa.

Kirill Melnikov does research in QCD aspects of hadron collider physics. He develops computational methods that are used to improve theoretical description of hard scattering processes in hadron collisions. Such improvements are important for e.g. the theoretical interpretation of the results expected from the LHC. His other research interests include B-physics and physics of the muon anomalous magnetic moment.

Emeritii
Gabor Domokos  and  Susan Kovesi-Domokos are working on the physics of the highest energy neutrinos, which are expected to be emitted from exotic astronomical objects, such as active galactic nuclei and gamma ray bursters.   To obtain more information about their research click on their names.
Bruce Barnett is a member of the CDF and CMS Collaborations. He contributes to the CMS Forward Pixel tracking system and to the silicon tracking and B-physics programs at CDF.

Barry Blumenfeld is a member of the CDF and CMS Collaborations. He is the leader of Frontier, a widely-distributed system to provide data-base information to remote compute nodes for both experiments.

Andrei Gritsan is a member of the BaBar and CMS Collaborations. He has studied several types of B => VV decays (V is a vector meson). The angular correlations in the final states provide insight into the heaviest elementary particle interactions in virtual loops and provide the best approach to the measurement of the CKM angle a. Gritsan also develops the methods of alignment of the silicon vertex detectors and is interested in searching for new phenomena at the LHC.

Petar Maksimovic's interests revolve around b-hadrons. On CDF, he studies the production, decay, and properties of B mesons and b-baryons. Recent work has focused on Bs mixing, searches for excited mesons and baryons (B**, Lambda_b*, and Sigma_b), the measurement of the lifetime of Lambda_b baryon, and the understanding of fragmentation. At CMS, he plans to turn these studies on their head and use the understanding of decay and production of b-hadrons gained from B physics in the measurement of the energy of fast b-quarks originating from decays of the Higgs boson and the top quark.

Morris Swartz is a member of the CMS Collaboration. He spends his time modeling the silicon pixel sensors used in the CMS pixel tracking system and using his model to produce optimal offline reconstruction and simulation codes. He is keenly interested in searching for manifestations of supersymmetry and extra-dimensions at the LHC.

Chih-Yung Chien is an Emeitus Professor in the department.
