“Fully Leptonic Charmonium Decays using the PANDA Detector at FAIR “
Olivia Mativi
Senior, Physics
Abstract
The Antiproton Annihilation at Darmstadt (PANDA) fixed-target particle experiment in Germany consists of the High Energy Storage Ring (HESR) and the PANDA particle physics detector. Anti-protons (p bar) circulating in the HESR strike essentially fixed protons (p) within the PANDA detector. Beam energies are selected such that these collisions produce charmonium (c cbar) particles, which quickly decay to lighter particles. The PANDA detector uses a sophisticated set of tracking chambers and particle-identification subdetectors to (1) measure the momenta and energies of all final-state particles, and (2) reconstruct charmonium decay chains. This poster presents initial Monte Carlo studies of the charmonium formation and decay process, p pbar → ψ(1S) → e+ e- and μ+ μ-, to test the PandaRoot software framework and evaluate PANDA detector performance. Special attention is given to the electromagnetic calorimeter and muon detection system. Detailed large-sample charmonium studies provide sensitive tests of Quantum Chromodynamics (QCD), the current most-productive model of the strong interaction. The PANDA experiment is currently under construction at the Facility for Antiproton and Ion Research (FAIR).

I am so sorry I can’t be there to see this presentation in person, Liv. You speak so freely and clearly on this topic, but with zero background in physics and no poster to look at, I will admit I am lost. Good luck tomorrow. I know you have worked very hard to get to this nuanced level of understanding.
