CERN VeloPix Detector Framework & Hyperparameter Optimiser

velopix

Velopix is a high-performance track reconstruction framework designed for processing collision data from the LHCb detector at CERN. It reconstructs particle trajectories by analyzing hit patterns recorded across multiple detector modules.

---

Overview

The package provides a complete reconstruction pipeline along with multiple algorithms and tools for validation and analysis. It is intended for use in high-energy physics data workflows, particularly for experiments that involve tracking particles across layered detector systems.
