Energy dependence of average transverse momentum in hadron production due to collective effects

TL;DR

This paper explores how the average transverse momentum in hadron production varies with energy in proton-proton collisions, proposing collective rotation effects and a transition to quark-gluon plasma as explanations.

Contribution

It introduces a novel explanation linking collective rotation of the transient state to energy dependence of transverse momentum in pp collisions.

Findings

Energy dependence observed in CMS data at LHC energies

Proposed collective rotation as a key factor influencing transverse momentum

Predicted flattening of the trend at higher energies indicating QGP formation

Abstract

Motivated by the first measurements of the experiment CMS at the LHC at $\sqrt{s}=0.9$ and 2.36 TeV, we discuss energy dependence of average transverse momentum of the secondary particles in hadron production in pp collisions. We suggest a possible explanation of this dependence as a result of collective rotation of the transient state and associate its further possible decrease with flattening off at higher energies with transition to the genuine QGP state of matter.
