Variation of Multiplicity Distributions for Mean Transverse Momentum with Cutoff in Hardon-Hardon Collisions

  • Using the three-fireball model, the multiplicity distributions for mean transverse momentum in hardon-hardon collisions at s=22GeV is investigated. We find that the change from negative to positive with increasing the transverse momentum cutoff comes from the following fact the rising scope of mean transverse momentum of hardon produced by side-fire balls with increasing the cutoff is greater than that of central fire balls.

Abstract: Using the three-fireball model, the multiplicity distributions for mean transverse momentum in hardon-hardon collisions at s=22GeV is investigated. We find that the change from negative to positive with increasing the transverse momentum cutoff comes from the following fact the rising scope of mean transverse momentum of hardon produced by side-fire balls with increasing the cutoff is greater than that of central fire balls.
