You have reached the home page of the University of Louisville's High Energy Physics (HEP) group. Currently, the group actively participates in the Belle II experiment, with recent activity and in some cases continuing membership in the Mu2e, ATLAS, and BABAR experiments, searching for signatures of physics beyond our current Standard Model of particle physics (AKA: "New Physics").

Mu2e is an experiment to search for a rare process - direct muon conversion to an electron. It is still in the development and construction phase at the Fermi National Accelerator Lab near Chicago. ATLAS is a very large general-purpose collider detector operating at the energy frontier at the Large Hadron Collider in the CERN Laboratory in Geneva, Switzerland. ATLAS is one of the two experiments that discovered the Higgs Boson in 2012. The Large Hadron Collider is foreseen to be the only location to discover lepton flavor violation in Higgs decays, if it exists. The BABAR Experiment took data on electron-positron collisions from 1999 to 2008 at the SLAC National Accelerator Laboratory in Palo Alto, California. We joined Belle II in 2018. In many ways, it is the logical successor to BABAR, except that it is situated at the KEK laboratory in Japan and will provide approximately 100 times the data sample of BABAR, allowing a much more precise look into phenomena that may give us hints into New Physics.

The group's work with Mu2e has so far been focused on developing the software framework, especially software pertaining to the detector's geometry as well as simulation, alignment, and documentation. We are also involved in studies of backgrounds due to radiative pion capture. Dr. Brown is leading these efforts.

The group's current activities on ATLAS include work on data mining and statistical analyses of the Higgs boson. We have also been involved in inner tracker simulation and upgrade tracking development work for the Phase 2 upgrade during the high luminosity run at HL-LHC. Dr. Banerjee leads this effort.

Brown and Banerjee have joined efforts to now work on Belle II, where they will work on the KLM detector, its readout middleware, and calibration and testing of its particle identification. They will also work on exciting analyses including searches for exotic particles - including dark matter candidates - and rare decays of the tau lepton. An application to join the group can be found here. We suggest you use the free Acrobat Reader available at

Recent News


We congratulate our own Professor Swagato Banerjee for receiving a US ATLAS Distinguished Researcher Award! The award will be used to support his important work on design and simulation of the Inner Tracker for upgrade of the ATLAS detector. Much of his work will be performed at the Lawrence Berkeley National Laboratory in Berkeley, California.

Welcome New Group Members!

We welcome new graduate student members Atanu Pathak, Diptaparna Biswas, Anjali Kanwar, Matthias Scott-Jones, Joe Leibson to the group! Welcome new undergraduate student Connor Cummings! And welcome to Dr. Phuong Dang as a new postdoc! It is great to have you all on board!

Intensity Frontier Fellowship

Congratulations to our own Dr. David Brown who received a Fermilab Intensity Frontier Fellowship for his work on Mu2e. Brown will use the fellowship to reside at Fermilab in the latter half of 2017 for work on developing Mu2e software.
