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

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.
