International Symposium on Very High Energy Cosmic Ray Physics

Cosmic-ray and particle physicists got together to discuss the latest developments in the field of high energy hadron collisions of cosmic ray particles in the 18th International Symposium on Very High Energy Cosmic Ray Interactions (ISVHECRI). The Symposium took place at CERN, from 18 to 22 August 2014 and from the CERN side it was co-chaired by Michelangelo Mangano and Albert de Roeck. About 150 scientists attended the Symposium.

ISVHECRI began in 1980 in Nakhodka, Russia, and takes place every two years. It welcomes scientists involved with high energy accelerators and colliding beam facilities from universities and institutes worldwide and has been organized in four continents so far: Asia, Europe, North America, and South America. The Symposium was launched to provide an optimal platform for the discussion on high energy cosmic ray research and related topics, including all aspects of very, and extremely, high energy cosmic ray studies with air showers. A special point of attention at ISVHECRI are the accelerator studies of hadronic interactions at very high energies and the consequent interpretation of the cosmic ray data as well as the understanding of hadronic interactions from cosmic ray data.

In the previous Symposium, which took place in Berlin in August 2012, the first detailed results from the LHC  were presented. This year the LHC experiments presented a plethora of high precision measurements with relevance for cosmic ray physics at the meeting.

The programme of this year's Symposium consisted of invited review talks, highlight talks, and posters selected from the submitted abstracts. The sessions focused on recent accelerator data and results, hadronic cross sections, multiparticle production, hadronic-interaction models, extensive air showers, high-energy cosmic-ray data, exotic phenomena, and muon and neutrino fluxes.

Paolo Lipari of INFN gave a very inspiring overview talk, concluding the Symposium, with a review of much of the new results, and highlighting the present enigmas in the field with a talk on “open questions and future challenges”.
