Evidence for unusual events in high energy cosmic ray interactions

Abstract

Anomalous events with a large transverse momenta PTP_T were found for all secondary particles in an analysis of experimental data on cosmic ray interactions at E0>51013eVE_0 > 5\cdot 10^{13} eV. In order to clarify the underlying mechanism of these events, the intermittency analysis of interactions with both large and usual transverse momentum was performed. It is shown that behavior of intermittency indices ϕ(q)\phi (q) as a function of rank factorial momentum qq for such interactions is very peculiar. The indices show slight growth for the events with large transverse momenta for all secondary particles in contrast with the fast growth for events with normal average transverse momenta for final particles. The significant difference in the behavior of intermittency indices gives strong evidence on the existence of the new class of hadron interactions with large PTP_T for all secondary particles in the event. A possible interpretation of these anomalous events as a manifistation of Color Glass Condensate in high energy hadron-hadron interactions is given.
