The Accelerator Data - Cosmic Ray Monte Carlo Interface;an Update

摘要

At the Hamburg ICRC 2001,the need for accelerator data at equivalent cosmic ray energies of a PeV and greater for the verification and refinement of Monte Carlo models of primary cosmic ray interactions was discussed.This presentation is an update on subsequent interactions and discussions of this important topic over the past two years.In 2002,the NEEDS Workshop in Karlsruhe and sessions at the XII International Symposium on Very High Energy Cosmic Play Interactions at CERN focused on these issues.While no single,comprehensive experiment is scheduled which would answer all questions raised in these discussions,there are relevant initiatives and activities at each of the major hadron collider laboratories which merit recognition and support by the cosmic ray com-munity.
