Periodic Reporting for period 1 - INTREPID (INnovative TRiggEr techniques for beyond the standard model PhysIcs Discovery at the LHC)

Periodo di rendicontazione: 2023-10-01 al 2026-03-31

Sintesi del contesto e degli obiettivi generali del progetto

The INTREPID project aims to transform how particle physics experiments detect rare phenomena that could reveal new physics beyond the Standard Model. At the High-Luminosity Large Hadron Collider (HL-LHC), scientists seek answers to fundamental questions such as the nature of dark matter and the origin of neutrino masses. These searches often involve long-lived particles (LLPs), which produce unusual signatures that traditional detection systems struggle to identify. INTREPID addresses this challenge by developing innovative trigger technologies capable of recognizing these elusive signals in real time. By enhancing the Level-1 Trigger system of the CMS experiment, the project will significantly improve sensitivity to LLPs, paving the way for discoveries that could transform our understanding of the Universe. Beyond particle physics, INTREPID’s advances in hardware acceleration and machine learning have potential applications in other sectors requiring ultra-fast data processing.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

Over the reporting period, INTREPID delivered major technical and scientific milestones across three work packages.

1) Simulation and Benchmarking (WP1): Developed advanced Monte Carlo simulations and a standalone Geant4-based framework to validate new algorithms. These tools enable precise performance studies under HL-LHC conditions.
2) Muon Shower Triggering (WP2): Implemented a clustering algorithm to detect high-multiplicity hit patterns in the CMS muon system, improving efficiency for high-energy muons significantly Firmware demonstrators confirm compliance with strict latency requirements.
3) Graph Neural Networks (WP3): Designed and trained models for reconstructing displaced muons using hit-based pattern recognition. Hardware prototypes using FPGA and ACAP platforms demonstrate feasibility for real-time deployment.

INTREPID also introduced a continuous integration workflow for firmware development and explored FPGA-based acceleration of physics simulations, opening new avenues for high-performance computing. Results have been presented at leading international conferences and published in peer-reviewed journals.

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

INTREPID achieved breakthroughs that push the boundaries of current technology. The muon shower algorithm represents a novel approach to recovering high-energy muons that standard triggers at the LHC miss, ensuring accurate momentum reconstruction even at multi-TeV scales. The integration of Graph Neural Networks into real-time trigger systems marks a paradigm shift, enabling sophisticated pattern recognition under stringent latency constraints. Unexpectedly, the project demonstrated that components of event generation software can be mapped to FPGA hardware, suggesting the possibility of real-time physics simulation—a transformative concept for data-intensive research. These innovations not only advance particle physics but also have cross-disciplinary potential in fields such as industrial process control and renewable energy forecasting. Future steps include large-scale validation, firmware optimization for AI models, and exploring commercialization opportunities through industry collaboration.
