Entropy scaling and thermalization in hadron-hadron collisions at LHC

TL;DR

This paper demonstrates that the entropy scaling in hadron-hadron collisions holds at LHC energies and predicts that at higher energies, particle production will be predominantly chaotic, implying collective behavior in such collisions.

Contribution

It shows the validity of entropy scaling at LHC energies and predicts the dominance of chaotic particle production at higher energies, indicating collective phenomena.

Findings

Entropy scaling is valid up to 2.36 TeV data.

Almost all particles will be produced chaotically at higher LHC energies.

Collective behavior is expected in hadronic collisions at high energies.

Abstract

The recent LHC data have once more brought the issue of the formation of thermalized state of matter in hadron-hadron collisions into the forefront. In this letter, we have shown that the scaling of the information entropy of the chaotically produced particles is valid up to recently available data from p+p collisions at $\sqrt{s}$ = 2.36 TeV obtained by ALICE experiment. We predict that at the highest energies projected for LHC, almost all the particles will be produced chaotically, indicating that a collective behavior should be observed in hadronic collisions, as indicated by one of present authors quite some time ago.
