Influence of the Effects of Color Reconnection and the Formation of Hadronic Jets on the Distribution of Charged Particles over the Transverse Momentum in pp-Collisions at the Energies of the Large Hadron Collider

Abstract

Dependences of the average transverse momentum of charged particles on rapidity $$y$$ and pseudorapidity $$\eta $$ are obtained, and the influence the effects of color reconnection and the formation of hadronic jets have on these dependences is studied. It is shown that the result depends largely on the interval of which physical quantity (rapidity or pseudorapidity) particle distributions over the transverse momentum are considered. It is important to compare theoretically calculated distributions to experimental data. It is shown in particular that allowing for the kinematic factor which arises in describing the distribution of particles over the transverse momentum in the specified pseudorapidity interval considerably influences the description of experimental data on pp-collisions at energies of $$\sqrt s = 7$$ TeV in the Large Hadron Collider.
