Research Report: Hunting Ghost Particles at CERN
Preview
This report is the longer, more detailed version of the poster I shared earlier this summer: same project, same detector, but with the full story behind it, from the physics motivation, to how I actually built and debugged the analysis, to everything I found along the way.
Coming in, I knew almost nothing about how particle detectors or their software actually work. By the end, I'd built a full pipeline to reconstruct particle trajectories and measure detector performance, and I ran into some genuinely interesting surprises: a faulty electronic part, a quirky structural feature of the detector, and a clear performance difference depending on which type of particle passed through, each requiring real detective work to explain.
If you're curious about the details, or just want to see what a summer of hands-on physics research actually looks like day to day, the full report is attached below!
