The 15th International Conference on Hypernuclear and Strange Particle Physics (HYP2025) will take place in Tokyo, Japan, from September 29 (Monday) through October 3 (Friday), 2025.

The HYP conference series brings together theoreticians and experimentalists working on hadron processes and nuclear systems

containing strangeness, from single to multi-strangeness systems, and from few-body systems to neutron stars. The topics of the HYP

conference have been extended to related fields such as low-energy aspects of QCD, dense and cold matter, as well as hadronic and nuclear systems with heavier flavors.

HYP2025 will be the fifteenth in the series of HYP conferences which were initiated in 1982 in Heidelberg and held periodically every three years. The recent conferences were succesfully held and rotated between Japan, Europe, and U.S.A (HYP2003 in JLab, U.S.A HYP2006 in Mainz, Germany, HYP2009 in Tokai, Japan, HYP2012 in Barcelona, Spain, HYP2015 in Sendai, Japan, HYP2018 in Portsmouth-Norfolk, U.S.A, HYP2022 in Prague, Czech).

First Announcement

Date: September 29 -- October 3, 2025

Place: Hongo-Campus, The University of Tokyo, Tokyo, Japan

The scientific program will be organized under the following topics:

1.   Production, structure and decay of hypernuclei

2.   Multistrange systems

3.   Interactions of mesons and baryons with strangeness

4.   Strangeness in hadron structure

5.   Strange mesons in nuclei

6.   Strangeness in astrophysics and in extreme forms of matter

7.   Heavy flavor systems

8.   Hypernuclei in heavy ion collisions

9.  Future experiments and facilities

The scientific program comprises invited talks in the plenary and parallel sessions, and contributed papers in the parallel and poster sessions. The oral presentations in the parallel sessions are selected from the contributed abstracts. The abstracts submission will be announced later.

Now registration/abstract submission page was opened.

Participants will arrange their own accommodation by themselves.

Regarding the hotel secured by the organizing committee, reservations can be made through the registration page, as long as rooms are available.
