The XXXIIII International Conference on Photonic, Electronic, and Atomic Collisions will be held in Sapporo, Japan, from July 29 to August 5, 2025. Sapporo is one of the largest cities in Japan, and located on the northern island of Hokkaido in Japan. The meeting will be held at teh Sapporo Convention Center, and a set of tutorials on July 29, 2025, will be held at Hokkaido University.

ICPEAC 2025 is expected to bring together more than 500 scientists from all over the world. Topics of the meeting will include

• Photon impact at weak fields (synchrotron, FEL)
• Photon impact at strong fields (femto/attosecond physics)
• Electronic collisions with atoms, molecules, and ions
• Collisions between ions, atoms, and molecules
• Antimatter and other exotic particle collisions
• Field-assisted collisions
• Ultracold atomic and molecular physics
• Collisions involving surfaces and condensed matter
• Related topics and experimental techniques
