20th International Symposium
on Very High Energy Cosmic Ray Interactions


Monday 21st – Friday 25th, May, 2018

Noyori Conference Hall, Nagoya University, Nagoya, Aichi, Japan


First Bulletin January 10th 2017


Dear possible participants,  


On behalf of the Organizing Committee, it is our pleasure to announce that the 20th International Symposium on Very High Energy Cosmic-Ray Interactions (ISVHECRI 2018) will be held at Nagoya, Japan, May 21 - 25, 2018. We would like to invite you to attend the symposium and to contribute to the program.   ISVHECRI is a biennial international conference series launched in 1980 at Nakhodka (Russia). The scientific aspect of the series is to focus on the high energy hadronic interaction of cosmic-ray particles and related topics including any high energy cosmic-ray research. The Symposium will highlight the understanding of hadronic interactions from cosmic-ray data as well as the studies of hadronic interactions at colliders and beam facilities, in particular at the LHC and RHIC.  This symposium series serves to strengthen the interaction between accelerator-based and cosmic-ray communities especially with regard to very high-energy phenomena.

Date:         Monday May 21 – Friday 25, 2018   

Place:        Noyori Conference Hall, Nagoya University, Nagoya, Japan  

Web site


Topics covered in this symposium include:

- EAS results relevant to Particle Physics

- Accelerator results relevant to Cosmic Ray Physics

- Emulsion chamber & Hybrid experiment results

- LHC pp and Heavy Ion Physics

- Exotic phenomena, manifestation of “New Physics” beyond the Standard Model

- Hadronic cross sections, multiparticle production & hadronic interaction models

- Space experiment data related to high energy interactions

- Matter-Antimatter asymmetry

- New EAS experimental installations

- High energy neutrino and muon fluxes

- High and super high energy cosmic rays, origin & observation
