- Antiparticle Production at BELLE and BELLE-II
Detection of antiparticle cosmic rays can be a key way to search for exotic sources of antimatter in our universe such as dark matter annihilation. Cosmic-ray antideuterons (an antiproton and antineutron bound together) are particularly good to look for since they are infrequently produced by non-exotic sources. However, the mechanism of their production from antiprotons and antineutrons---called coalescence---is poorly understood. We can study this process in the laboratory using decays of upsilon mesons (bound states of bottom and antibottom quarks) produced at the Belle experiment in Tsukuba, Japan (and in the near future at the Belle II experiment). To do this, we need to measure the momentum spectra of antideuterons and antiprotons produced by decaying upsilons. The task of this thesis work is to analyze existing data from the Belle experiment (and plan for future data from the Belle II experiment) to search for antiprotons and antideuterons in upsilon decays.
Tasks
• Learn how an analysis is conducted at a high-energy physics experiment
• Compose the analysis using C++ / Python
• Check the accuracy of the analysis using simulated data
Prerequisites
Experience in C++ or Python programming is helpful, but not required.
