Multiplicity dependence of the transverse-momentum spectrum for centrally produced hadrons in antiproton-proton collisions at√s =1.8TeV

Abstract
The transverse momentum of charged particles produced within the pseudorapidity range η=-0.36 to +1.0 has been measured in p¯p collisions at √s =1.8 TeV. The charged-particle multiplicity of each event was measured with a 240-element cylindrical hodoscope system covering the range -3.25<η. The average transverse momentum as a function of the average charged-particle density per unit of pseudorapidity is presented. Events are observed with average charged-particle density as high as 32 per unit of pseudorapidity.
