Bennett research group

The Bennett group in the Department of Physics and Astronomy at the University of Mississippi is part of the Belle II experiment at the SuperKEKB asymmetric-energy electron-positron accelerator, based in Tsukuba, Japan. The experiment is part of a search for physics beyond the Standard Model of particle physics, which describes the known particles and their interactions. Belle II operates at the "intensity frontier" in which high luminosity experiments collect massive data samples that analysts can use to search for rare or forbidden processes. Any discrepancies between theoretical expectations and experimental measurements may indicate the presence of new physics.

Charm baryon physics

The next generation of particle physics experiments provides a unique opportunity to search for signs of new particles and interactions beyond the Standard Model (SM) of particle physics. The Bennett group searches for CP violation in charmed baryon decays using data from the Belle II experiment. Precision measurements will help to clarify the picture of CP violation in the charm sector and potentially open a window to physics beyond the Standard Model.

Belle II distributed computing

Experiment at the "intensity frontier" take advantage of massive data samples to search for new physics by making precise measurements of rare and forbidden processes. These experiments face significant challenges related to the management and use of the enormous expected data samples, often relying on computing resources distributed around the world via grid computing. The Bennett group provides vital support for Belle II distributed computing, including development of grid-based user tools, documentation and training, and operations support.
