Applied Physicist for ATLAS Trigger Reconstruction (EP-ATL-OSW-2026-124-GRAP)

The goal of this project is to introduce innovative selections into the ATLAS trigger system to improve the identification of events in difficult regions of the parameter space, including rare Standard Model processes and exotic signatures. In collaboration with NextGen doctoral students, the selected candidate will contribute to the development of the trigger menu for the High-Luminosity Large Hadron Collider (HL-LHC) era. The position is part of the Next Generation Trigger programme.

Your responsibilities

• Design new triggering algorithms and strategies, including alternative data flows and ML/AI-based approaches.
• Develop tools to support HL-LHC trigger menu studies.
• Simulate trigger selections and estimate trigger rates using data and HL-LHC Monte Carlo samples.
• Ensure that proposed solutions meet trigger menu constraints on processing resources and rate limits.
• Implement sol...
