From analysis of V0 events observed in an exposure of the National Accelerator Laboratory 30-in. bubble chamber to 303−GeVc protons, we obtain these results: (1) 〈nπ0〉 rises approximately linearly with n-, implying strong coupling of neutral and charged pions, while 〈nKS0〉 is less coupled to n; (2) γ, KS0, and Λ0 production cross sections are approaching a scaling limit by 303 GeVc; (3) within the limited statistics, dσdy is flat in the central region for KS0 and low-multiplicity γ events.

Results on multiplicities, topological cross sections, total particle production cross sections, and correlations between charged particle and π 0 production are presented for pp interactions at 12 and 24 GeV/ c incident laboratory momentum. Inclusive production of π ± , K s 0 , p , Λ, Σ ± and Λ is studied; particle spectra are shown in single and double differential form and are compared, in different kinematic regions, with data obtained at other incident momenta and with other beam particles.

Inspire Record 131498 DOI 10.17182/hepdata.34804

We present a study of the inclusive reactions p p → K S 0 X, ΛX and Λ X at 3.6 GeV/ c based on 35.4 events/μb. The cross sections are presented in terms of the Feynman variable, rapidity and the transverse momentum. The absolute value of the Λ polarization is found to increase with increasing p T of Λ. A comparison of the inclusive productions of K S 0 in p p and e + e − is presented.

Inclusive Production of K* (890), Sigma (1385) and S* (993) Resonances in anti-p p Interactions at 12-GeV/c Incident Momentum

Nucl.Phys.B 140 (1978) 220-234, 1978.
Inspire Record 135964 DOI 10.17182/hepdata.35033

The reactions p p → K ∗ (890) X , p p →Σ ± (1385) X and p p → S ∗ (993) X at 12 GeV/ c incident momentum have been studied using 19 000 events with a visible V 0 decay in BEBC. Inclusive production cross sections of these resonances as a function of transverse momentum and rapidity are presented. The contribution of annihilation to the production of the K ∗ (890) is investigated from a comparison with the corresponding pp data.

Single Particle Inclusive Spectra of Charged Particles in anti-p p Interactions at 22.4-GeV/c

The Alma Ata-Dubna-Helsinki-Kosice-Moscow-Prague collaboration Boos, E.G. ; Samoilov, V.V. ; Takibaev, Zh.S. ; et al.
Nucl.Phys.B 121 (1977) 381-392, 1977.
Inspire Record 109633 DOI 10.17182/hepdata.35465

The inclusive spectra for p p collisions at 22.4 GeV/ c are investigated. We show that the transverse momentum distributions resemble those in high-energy pp interactions and discuss the influence of annihilation processes on the p T 2 distributions. The invariant inclusive cross section for pions in the central region is found to be 28 ± 1 mb. A charge asymmetry is indicated by the y ∗ spectrum in the central region, the asymmetry parameter having the value 0.15 ± 0.01. Finally, we estimate the upper limit of the diffraction dissociation of the beam particle to be 3.68 −0.15 +0.45 mb.

Inclusive Production of Charged Pions in K- p Interactions at 32-GeV/c

The French-Soviet & CERN-Soviet collaborations Faccini, M.L. ; Barloutaud, R. ; Berard, A. ; et al.
Nucl.Phys.B 127 (1977) 109, 1977.
Inspire Record 119612 DOI 10.17182/hepdata.35284

Results are presented on the inclusive π ± production in K − p interactions at 32.1 GeV/ c . The invariant longitudinal distributions have been calculated both for π + and π − in the backward c.m. hemisphere and extrapolated in the forward hemisphere under some physical assumptions. The inclusive cross sections for π + and π − amount to 32.9 ± 1.5 mb and 35.0 ± 0.7 mb respectively. The energy dependence of the inclusive pion production has been analyzed in the framework of Mueller-Regge phenomenology both in the proton fragmentation and in the central region.

The Reactions K+ p --> Lambda x++ and K+ p --> anti-Lambda x++ at Incident Momenta of 8.2-GeV/c and 16.0-GeV/c

Chliapnikov, P.V. ; Ciapetti, G. ; Dunwoodie, W. ; et al.
Nucl.Phys.B 112 (1976) 1-51, 1976.
Inspire Record 109100 DOI 10.17182/hepdata.35646

Inclusive production of Λ and Λ in K + p interactions is studied at incident momenta of 8.2 and 16.0 GeV/ c . Cross sections and single-particle distributions are presented, the correlation between longitudinal and transverse momentum is investigated, and the dependence of average charge multiplicity on missing mass measured. For Λ production, early scaling is observed in the target fragmentation region when the data are presented in terms of ( M 2 - M th 2 )/ s and t , where M th is the threshold value of the missing mass M . Furthermore, a triple-Regge analysis in these variable yields an effective exchange trajectory which passes through the K, Q and L mesons. There is evidence for beam fragmentation in Λ and Λ production, but the contributions seem not to be dominant in the fragmentation region. Nevertheless, the parameter values in a triple-Regge description are estimated, and together with those for target fragmentation in Λ production, provide a complete description of the fragmentation contributions to the two reactions. Integration of the resultant distribution functions over the complete Chew-Low plot yields fragmentation cross sections increasing approximately as log s ; in addition the observed features of the x , p L and p T 2 projections and of the p L - p T correlation are well-described in the fragmentation regions. Central production contributions are isolated by subtracting the calculated fragmentation distributions

Inspire Record 101304 DOI 10.17182/hepdata.35578

From a study of 1226 neutral strange particles produced in pp interactions at 69 GeV/ c in the MIRABELLE hydrogen bubble chamber, we obtain the inclusive cross sections for K S 0 , Λ / Σ 0 , Λ / Σ 0 equal to 3.43 ± 0.23, 3.44 ± 0.2 and 0.16 ± 0.03 mb, respectively. The inclusive distributions are compared with corresponding data at other energies.

Inclusive V0 Production in anti-p p Interactions at 12-GeV/c

The Brussels-CERN-London-Mons-Orsay collaboration Bertrand, D. ; Johnson, D. ; Lemonne, J. ; et al.
Nucl.Phys.B 128 (1977) 365, 1977.
Inspire Record 120622 DOI 10.17182/hepdata.36137

Results are presented on the inclusive reactions p p → K 0 X , p p → Λ X and p p → Λ X at an incident antiproton momentum of 12 GeV/ c in BEBC. The cross sections are studied as functions of the Feynman scaling variable x , the rapidity, the transverse momentum of the V 0 and the missing mass squared. The dependence of the Λ and Λ polarization on x are also studied. Comparisons with proton-proton data at 12 GeV/ c are also made. Finally, events with two detected V 0 are analyzed in order to study correlations arising from the production of two strange neutral particles.
