Characteristics of $V^0$ and $\gamma$ Production in pp Interactions at 205 GeV/c

Jaeger, K. ; Colley, D. ; Hyman, L. ; et al.

Inspire Record 91136 DOI 10.17182/hepdata.24886

In an exposure of the Fermi National Accelerator Laboratory 30-in. bubble chamber to a beam of 205-GeV/c protons, we have determined total and differential cross sections for the inclusive reactions p+p→γ+X, π0+X, (K0K¯0)+X, Λ+X. Invariant distributions in x indicate that for γ, K0, Λ production, scaling has set in somewhere before 69 GeV. The γ differential cross sections are consistent with the relation dσdPu(π0)=12[dσdPu(π+)+dσdPu(π−)] for all Pu, where Pu=PL* or P⊥. The differential cross sections for Λ and K0 production indicate a break in the distribution at |t−tmin|=1.5(GeVc)2 and 0.5(GeVc)2, respectively. The Λ polarization is found to be - (0.25 ± 0.26), consistent with zero throughout the x region.

Multiplicities, topological cross-sections, and single particle inclusive distributions from p p interactions at 12-GeV/c and 24-GeV/c

The Bonn-Hamburg-Munich collaboration Blobel, V. ; Brandenburg, G.W. ; Fesefeldt, H. ; et al.
Nucl.Phys.B 69 (1974) 454-492, 1974.
Inspire Record 94379 DOI 10.17182/hepdata.32358

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.

Observation of Vector Meson Production in Inclusive p p Reactions

The Bonn-Hamburg-Munich collaboration Blobel, V. ; Fesefeldt, H. ; Franz, H. ; et al.
Phys.Lett.B 48 (1974) 73-76, 1974.
Inspire Record 80794 DOI 10.17182/hepdata.27994

We have measured cross sections, rapidity and transverse momentum distributions, and vector meson polarization for the reactions pp→ ϱ o +anything, pp→ ω +charged particles, and pp → K ∗± + anything at incident laboratory momenta of 12 and 24 GeV/ c . We discuss various consequences of our results as well as possible connections with lepton pair production.

The inclusive single-particle spectra of pi-, K0(s) and Lambda in proton proton collisions at 19-GeV/c

The Scandinavian Bubble Chamber collaboration Boeggild, H. ; Dahl-Jensen, E. ; Hansen, K.H. ; et al.
Nucl.Phys.B 57 (1973) 77-99, 1973.
Inspire Record 84068 DOI 10.17182/hepdata.32535

Data on the inclusive production spectra of K S 0 and Λ from proton-proton collisions at 19 GeV are presented and discussed in connection with the earlier studied inclusive π − production spectrum. The three single-particle spectra are compared with a crude two-center thermal model for the average radiation from the pp collisions.
