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
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
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
upgrade tracking development work for the Phase 2 upgrade during the
high luminosity run at HL-LHC.
Dr. Banerjee leads
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.

US ATLAS Award
October 31, 2017
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!
August 1, 2017
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
January 1, 2017
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.
