Quark Jets from Antineutrino Interactions II: Inclusive Particle Spectra and Multiplicities in the Quark Jets

We present results on inclusive particle production in the antineutrino charged current induced hadron jets observed in the Fermilab 15 ft bubble chamber. Fractional energy distributions, particle ratios and average multiplicities of the hadrons in the jets are measured. Ratios between the inclusive production rates of different mesons in the jets are studied to seek evidence for the d-quark origin of the observed hadrons. Good over-all agreement with the hypothesis of d-quark fragmentation with universal fragmentation functions obeying isospin systematics is established.

Neutral Pion Production in $K^+ p$ Interactions at 32-{GeV}

The French-Soviet & CERN-Soviet collaborations Azhinenko, I.V. ; Belokopytov, Yu.A. ; Borovikov, A.A. ; et al.
Nucl.Phys.B 162 (1980) 61-78, 1980.
Inspire Record 131232 DOI 10.17182/hepdata.8076

Inclusive and semi-inclusive distributions of γ's and π 0 's in the reactions K + p → γ + X and K + p → π 0 + X at 32 GeV/ c are presented and discussed. When compared to the inclusive π − production, the π 0 cross section is found to be significantly higher in low | x | and p T regions. The data are compared with other experiments and quark fusion model predictions.

Particle Multiplicities in K- p Interactions at 32-GeV/c

Nucl.Phys.B 124 (1977) 61-80, 1977.

The inclusive cross section and the average multiplicity are evaluated for most of the charged ( π ± , p, K ± ) and neutral (γ, π 0 , K 0 , K 0 , Λ, Λ , n ) particles produced in 32 GeV/ c K − p interactions; corresponding results are obtained for each charged topology separately. New results are given for the total charged multiplicity cross sections. The average longitudinal momentum of neutrals is found to be roughly equal to that of charged particles. The π + and π − multiplicity distributions are reconstructed and compared to the π 0 and to the total charged multiplicity distributions.
