Production of pi0 Mesons in K+ p Interactions at 8.2-GeV/c

Bartke, J. ; Eskreys, A. ; Figiel, J. ; et al.

Acta Phys.Polon.B 5 (1974) 689, 1974.

Inspire Record 90280 DOI 10.17182/hepdata.51679

Experimental results on $\pi^0$ production in $K^+$p interactions at 8.2 GeV/$c$ incident momentum are presented. Average $\pi^0$ multiplicities for given prong numbers are evaluated. They are consistent both with the corresponding results for pp interactions at 12 GeV/$c$ chosen for comparison because they have the same average prong number) and with a model where total multiplicity distributions are calculated from the Czyżewski--Rybicki formula and the charge branching ratios from the statistical model. Some averages over the $\pi^0$ momentum distribution are also evaluated. In particular it is found that $\pi^0$-s produced in two prong interactions go predominantly forward.

Inclusive production of ifπ ± , K ± and p has been studied near charm threshold for c.m. energies between 3.6 and 5.2 GeV. Differential and scaling cross sections together with particle multiplicities have been determinated. By comparing data below and above charm threshold the charm contribution to if π ± and K ± production has been extracted. A comparison has been made between inclusice p production and inelastic electron-proton scattering. To study differences between three-gluon annihilation and two-quark production of the spectra from J/ decay and from non-resonant production at 3.6 GeV has been compared.

Charged Particle Multiplicities in ($p p$) Interactions and Comparison With ($e^+ e^-$) Data

Nuovo Cim.A 65 (1981) 400, 1981.

Inspire Record 166765 DOI 10.17182/hepdata.37470

By using three different c.m. energies in pp interactions,$\sqrt s $, 44, 62 GeV, it is shown that the average charged-particle multiplicity <nch> sclaes with$\sqrt s $ once the correct hadronic energy available for multiparticle production,Ehad, is used as basic parameter. The pp data, analysed in this way, are compared with e+e− data at equivalent energies. The agreement is very satisfactory.

By using (pp) interactions at three different c.m. energies,$\left( {\sqrt 8 } \right)_{pp} $=30, 44, 62 GeV, it is shown that the average charged-particle multiplicity <nch>vs. the invariant mass of the hadronic systemm1,2 has the same behaviour as it hasvs. 2Ehad. Moreover, in both cases <nch> is shown to be nearly independent of$\left( {\sqrt 8 } \right)_{pp} $ and in good agreement with the average charged-particle multiplicity measured in the (e+e−) annihilation.

Absolute inclusive cross sections for$\bar pp$ interactions at 7.3 GeV/c are given. The data cover prong cross sections,V0, γ production and inclusive charged particle (p/π) production. Separation has been made into annihilation and non-annihilation components. Inclusive π+, π− production in the processes of$\bar pp$ annihilation and non-annihilation are compared with simple quark models.

INCLUSIVE RESONANCE PRODUCTION IN 7.3-GEV/C ANTI-P P INTERACTIONS

Whyman, B.M. ; Johnson, P. ; Mason, P. ; et al.

Z.Phys.C 12 (1982) 203-216, 1982.

Inspire Record 179887 DOI 10.17182/hepdata.16423

We present results on inclusive baryon and meson resonance production in$\bar pp$ interactions at 7.3 GeV/c. Total inclusive and semi-inclusive cross sections are given for Δ(1232),∑*(1385), ϱ0,f andK*±(892) production. For the meson resonances separation into annihilation and non-annihilation components has been made, the annihilation component being dominant at this energy. We find that the energy dependence of inclusive cross sections for ϱ0 production inpp interactions and$\bar pp$ non-annihilations shows a type of scaling behaviour previously reported for ϕ, ψ, ψ′ and ϒ production inpp interactions.Δ++, ϱ0 andK*± production are studied in terms of Feynmanx,y* andpT2. For the vector mesons we compare they* andx dependences with the predictions of simple quark models.
