"Due to the COVID-19 pandemic, we regret to announce that the ISVHECRI 2020 scheduled to be held during 4-8 June 2020 is POSTPONED. New dates will be decided after the situation returns to normal".
The 21st International Symposium on Very High Energy Cosmic Ray Interactions (ISVHECRI 2020) will be hosted by the Tata Institute of Fundamental Research at the site of the GRAPES-3 experiment in Ooty, India during June 4-8, 2020.

ISVHECRI is a biennial conference series supported by the International Union of Pure and Applied Physics (IUPAP). Its primary objective is to provide a forum for the discussion of very high energy interactions for the interpretation of cosmic ray data based on the information available from both accelerator and cosmic ray experiments. This unique series brings together cosmic ray physicists and scientists involved with high energy accelerators and colliding beam facilities.

Symposium topics:

  • High energy astroparticle physics results relevant to particle physics
  • Accelerator experiments relevant to cosmic ray physics
  • Space experiment results relevant to high energy interactions
  • Exotic phenomena & searches for new physics beyond SM
  • LHC pp & heavy ion physics
  • Cross-sections and interaction models
  • High energy neutrinos and muons
  • Simulation tools for cosmic ray & neutrino physics
  • Multi-messenger cosmic ray observations & interpretations
  • Future accelerators & cosmic ray experiments

The Symposium will consist of invited and contributed talks as well as poster presentations. All the talks will be organized in plenary sessions.
