Inclusive neutral pion production at forward angles at 4.5 GeV/ c per nucleon in α+C→ π0+x and α+Cu→ π0+x reactions

Abstract

Distributions for transverse momentum P ⊥ and cumulative number X of inclusive neutral pions are measured with a lead glass calorimeter in α+C→ π 0+x and α+Cu→ π 0+x reactions at 4.5 GeV/ cper nucleon. The target-mass dependence for π 0 production is presented.
