Transverse momentum spectra of charged particles produced within the pseudo-rapidity range of η= − 0.36 to + 1.0 have been measured in p p collisions at √ s=0.3, 0.54, 1.0, and 1.8 TeV. The spectra are presented as a function of event charged multiplicity within the range −3.25< η<3.25. We found that the slope in the low p t region is independent of center-of-mass energy and multiplicity while the slope at the high p t region shows a strong energy and multiplicity dependence.
