20th European Cosmic Ray Symposium - ECRS 2006, Lisbonne : Portugal (2006)
Coplanar emission near the LHC energy range (observed with XREC in the stratosphere)
J.-N. Capdevielle1, R. Attallah, M. Talai

The alignment of very high energy secondary cosmic rays was observed at both stratospheric and mountain altitudes by several X-ray emulsion chamber experiments. Extensive simulation with CORSIKA demonstrates that such phenomena can be explained by fluctuations with standard physics. However, in the case of two events observed in the stratosphere, specific features contradicts such explanation. According to the properties of those events with a minimal cascading, we explore the hints of new physics which could explain the alignment in terms of relativistic strings and diquark breaking. One description of the consequent coplanar emission expected in colliders is proposed.
