Development of a High-Resolution Muon Calibration Sample for the IceCube Upgrade — •Simon Pick — DESY, Zeuthen

The IceCube Upgrade will deploy nearly 800 new optical sensors in a closely spaced region within the IceCube DeepCore volume, enabling an unprecedented view of atmospheric muons and neutrinos. This dense instrumentation may offer the opportunity to identify muon tracks with exceptionally high angular precision through direct detection. Such events could serve as powerful calibration sources for detector response and angular reconstruction algorithms.

In this contribution, I will present ongoing work toward the development of a high-resolution muon calibration sample. This includes progress on characterizing muon-induced sensor responses through laboratory measurements and simulation, with a particular focus on the development of a new dedicated calibration stand. More broadly, I will provide an overview of the current status and outline the next steps toward the sample development and studies of potential improvements in reconstruction performance.
