24th International Workshop on Advanced Computing and Analysis Techniques in Physics Research
The 24th International Workshop on Advanced Computing and Analysis Techniques in Physics Research (ACAT2027) will be held from Friday, March 5th, to Wednesday, March 10th, 2027, at Tokyo City University’s Setagaya Campus. The workshop will be jointly organized by the Institute for Computational Physics and Mathematics (ICEPP) at the University of Tokyo and the Advanced Research Laboratory (ARL) of Tokyo City University.
This edition of ACAT, held in Japan for the first time in 24 years since ACAT03 at KEK, builds on the legacy of AIHENP and the long-standing ACAT International Workshop Series. ACAT2027 will serve as a platform for exchanging ideas on artificial intelligence, machine learning, high-performance and scalable computing, and advanced analysis techniques that are driving scientific progress across various disciplines.
AI and Advanced Computing from Particles to the Cosmos
Fundamental physics is witnessing a paradigm shift, where artificial intelligence and advanced computing are no longer auxiliary tools but central drivers of discovery. Across various research fields, including particle, nuclear, astrophysics, and cosmological studies, modern computational methods are revolutionizing the integration of theory, experiment, and observation. ACAT2027 will delve into this transformative journey, exploring for the first time, its impact across the entire spectrum of scales, from the tiniest particles to the grandest structures in the universe. The conference will explore this groundbreaking topic through four parallel sessions and plenary talks.
In experiments and observations, AI is redefining the boundaries of precision, efficiency, and responsiveness. Advanced reconstruction, real-time event selection, intelligent calibration, and automated data-quality monitoring are becoming indispensable components of contemporary facilities. From collider detectors to neutrino observatories and gravitational-wave instruments, AI-driven methodologies are enhancing sensitivity while effectively managing the immense scale and complexity of data streams generated by next-generation technologies.
These advancements are intrinsically linked to progress in computing itself. Heterogeneous architectures, high-performance and distributed computing, edge and real-time processing, and specialized hardware such as GPUs, FPGAs, TPUs, and ASICs are shaping the design and deployment of algorithms. Collaborative efforts across physics, software, and hardware, coupled with digital twins, foundation models, and autonomous control systems, are enabling the development of more adaptive, efficient, and intelligent research infrastructures.
The workshop will underscore the convergence of communities dedicated to advanced computing within the realms of particle physics, nuclear physics, astrophysics and cosmology, gravitational-wave science, and accelerator research. The transformative impact of AI and computational methods is reshaping the design of experiments, the analysis of data, and the interpretation of theoretical models in relation to observations.
Nobel Symposium and Thematic Symposia
To foster focused discussions and interactions, the program will feature a Nobel symposium centered around keynote speakers and round-table discussions. Additionally, a new type of parallel session, known as mini-symposia, will be introduced to facilitate more concentrated discussions on specific AI topics. These sessions will encourage cross-disciplinary dialogue on shared challenges, including:
-
AI for integrated theory-experiment workflows
-
Intelligent, autonomous, and real-time experimental systems
-
Resource-aware and edge-optimized machine learning
-
Scalable software and computing models for future facilities
-
Trustworthy AI, uncertainty quantification, and reproducibility
ACAT2027 aims to advance a unified understanding of architectural AI, applied AI, and advanced computing as fundamental pillars of discovery in fundamental physics by strengthening connections across fields and bridging for the first time scales from particles to the cosmos.
