The 24th International Workshop on Next Generation Nucleon Decay and Neutrino Detectors (NNN25) will be held in Sudbury, Ontario, Canada. The workshop location will be split between SNOLAB (pre-workshop Monday and Tuesday, hosted by McGill University) and the main workshop at Places Des Arts (Wednesday to Friday). 

NNN25 is jointly organized by SNOLAB, McDonald Institute, and McGill University. We are grateful to the Canadian Institute of Nuclear Physics (CINP), which has generpusly provided financial support for a limited number of Canadian highly qualified personnel (HQP), connected to CINP, to participate in the conference at reduced cost.

Over the last 25 years, the NNN series of workshops has been providing the international community a forum for in-depth discussions on future large-scale detectors for research on nucleon decay and neutrino physics since its inaugural workshop in 1999 at Stony Brook (NY). The main physics topics of the workshop include: searches for proton decay, CP violation in the lepton sector, determination of the neutrino mass hierarchy, and observation of neutrinos from core-collapse supernovae.

Registration

Registration is open as of June 10, 2025. For more information about registration process and fees, please see the dedicated REGISTRATION page from the main menu (left).

Abstract Submission

Individuals and collaborations are encouraged to submit abstracts, which the International Scientific Advisory Committee (ISAC) will then review, select, and organize into sessions. Abstracts can be for posters or talks. The ISAC may discuss with submitters whether their abstract could be converted into a poster or talk, as appropriate. Please see the dedicated Abstract submission system below (or available from the main menu, left).

Workshop Poster

Please share this poster with colleagues to help advertise the event and encourage participation.
