HE Stratosphere Event of 1975 Revisited: the Difference between the Patterns of Astroparticle Interaction and LHC Nucleus-Nucleus Collision

Abstract

The event of astroparticle collision at high energy was detected in 1975 during the balloon flight in stratosphere. The hundred particle tracks in x-ray films have been re-analyzed in the style of LHC experiments: rapidity distributions of charged particles and transverse mass spectra of multi particle production have been built. The comparison of multiple histograms with the knowledge accumulated in Quark-Gluon String Model gives us the conclusion that it was the carbon nucleus collision with the matter of atmosphere at the c.m.s. equivalent energy √ s ≥ 5 TeV. After QGSM analysis of these scarce data, we know the following: 1) the value of maximal rapidity of one projectile proton and 2) the density of particle multiplicity in the central rapidity region. Such a way, we can practically distinguish how the astroparticle interaction is similar to, or differs from average A-A collision event at LHC. The data include some features of new physics, as an example, it may be baryonic DM particle collision. Previously, the suggestion was done that baryonic Dark Matter cannot be reproduced in accelerators. It appears in the space at a huge mass density near the giant objects like Black Holes. Finally, we conclude that the cosmic ray experiments on the high altitude in atmosphere are, on one hand, good supplements to the LHC measurements. On the other hand, they are able to observe events of new astroparticle collision in the full kinematical region.

“…It is natural to expect also a second particle with a similar high transverse mass, which was obviously lost beyond the scope of detector. 3) The rapidity distribution with smaller binning, see [10], shows few rapidity peaks of triple-Pomeron type in the spectrum. Such feature belongs to strongly connected nucleon system decayed for few hadrons with different masses.…”

“…The spot with certain darkness gives us the energy of the particle produced in the interaction. A more detailed description can be found in the preprint [10]. The positions of 106 observed dark spots are recorded.…”
