摘要：

Transverse momentum spectra of charged particles produced within the pseudo-rapidity range of eta = -0.36 to +1.0 have been measured in pBARp collisions at square-root 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 < eta < 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.
