Query: Description of High-Energy pp Collisions Using Tsallis Thermodynamics:
  Transverse Momentum and Rapidity Distributions   A systematic analysis of transverse momentum and rapidity distributions
measured in high-energy proton - proton (pp) collisions for energies ranging
from 53 GeV to 7 TeV using Tsallis thermodynamics is presented. The excellent
description of all transverse momentum spectra obtained in earlier analyses is
confirmed and extended. All energies can be described by a single Tsallis
temperature of 68 +/- 5 MeV at all beam energies and particle types
investigated (43 in total). The value of the entropic index, q, shows a wider
spread but is always close to q approx 1.146. These values are then used to
describe the rapidity distributions using a superposition of two Tsallis
fireballs along the rapidity axis.
  It is concluded that the hadronic system created in high-energy p - p
collisions between 53 GeV and 7 TeV can be seen as obeying Tsallis
thermodynamics.
