Neutrino Interactions for Current and Future Experiments

27 Oct 2025, 13:00 → 29 Oct 2025, 18:00 Asia/Tokyo

4th Building 1F Seminar Hall (KEK Tsukuba Campus)

International workshop "Neutrino Interactions for Current and Future Experiments" 
will take place at KEK, Tsukuba, Japan from October 27(Mon) to 29(Wed). 
This workshop is intended to provide an opportunity where theorists and experimentalists 
get together and intensively discuss the neutrino-nucleon and neutrino-nucleus interactions 
and their applications to current and future neutrino experiments. 
All talks are by invited speakers.
