INFN ELOISATRON PROJECT 44TH Workshop Project Director: A. Zichichi QCD at Cosmic Energies: The Highest Energy Cosmic Rays and QCD The aim of the Workshop is to discuss issues of common interest for the highest energy cosmic ray physics (in particular, near the GZK cutoff) and forward physics at LHC, in particular those related with a new regime of strong interactions expected to emerge at these energies. The QCD understanding of this new regime has implications for modeling cosmic showers. Furthermore, cosmic ray experiments may provide an important insight into quark-gluon interactions at extreme gluon densities. The Workshop will bring together experts in high energy QCD and cosmic ray physics in view of expanding the mutually beneficial interface between experiments planning to explore forward physics at LHC and highest energy cosmic ray experiments.
