The Wisconsin High Energy Physics group conducts research on the
experimental and theoretical frontiers of particle physics.
Profs. Carlsmith, Herndon and Pondrom search for the Higgs boson
using the CDF detector at the Fermilab Tevatron where some possible
masses for a Standard Model (SM) are being ruled out. They study Bs
oscillations, rare B-decays, and high-mass jets. They have leading
responsibilities in the B-Physics and Higgs physics analysis as well
as responsibility for the CDF intermediate angle muon system.
After their BaBar experiment at the SLAC B-factory discovered CP
violation phenomena in the B meson sector, Profs. Dasu and Prepost work
to firmly establish the CKM quark mixing formalism in the Standard
Model (SM) and to determine very tight constraints on physics beyond
the SM. They also have a significant involvement in detector and
accelerator R&D for the ILC.
Prof. Heeger is working on construction of the Daya Bay Reactor
Antineutrino Experiment and starting in 2010 will measure the electron
neutrino coupling to the third mass eigenstate and the corresponding
unknown neutrino mixing angle θ13.
Profs. Mellado, Pan and Wu are working on the ATLAS experiment
and Profs. Carlsmith, Dasu, Herndon and Smith are working on the CMS
experiment, both at the CERN LHC. These groups completed 15 years of
studies, design, construction, installation, commissioning and are now
operating major components of their detectors, as well as simulation
and computing facilities for physics analysis. The ATLAS group has
leading roles in the silicon and pixel readout driver, high level
trigger (HLT), Higgs physics studies and software and computing. The
CMS group has leading responsibilities in the Trigger (Level-1 and HLT)
and Endcap Muon systems, physics coordination, software and computing.
Both groups are looking forward to discoveries such as the Higgs boson,
supersymmetry, exotic particles, extra dimensions or whatever else
emerges in this new regime. They are also working on the simulation
and detector upgrade program for the Super LHC.
Profs. Barger, Chung, Everett, Halzen, Han, Ramsey-Musolf and
Petriello are applying their internationally recognized expertise on
calculations of new physics models and SM backgrounds to interpret
the new data from the experimental frontier. With the imminent
turn-on of the LHC, collider physics phenomenology is a central focus
and this group is performing these important calculations and the
training of students and postdocs to perform these calculations
in the future. Prof. Petriello is developing novel methods for
ultra-precise calculations in quantum field theory and applying them
to Tevatron and LHC phenomenology. Prof. Ramsey-Musolf is developing
theoretical methods to compute the matter-antimatter asymmetry of
the universe and is investigating the implications of ultra-precise
tests of fundamental symmetries for physics beyond the Standard
Model. Prof. Chung is studying the implications of dark matter and
dark energy theories for observations at colliders and particle
astrophysics. He is also studying the consequences of his new field
theories for general relativity, cosmology and particle physics and
exploring electroweak baryogenesis.
Profs. Hashimoto and Shiu are investigating the extensive range
of topics in string theory ranging from its mathematical formulations
to phenomenological applications. Their research aims to provide
new insights and a foundation for studying quantum gravity, strong
interaction physics, physics beyond the Standard Model, and the
