New experimental results are presented on inclusive production properties of\(\bar \Sigma ^{ *+ } \)(1385) and\(\bar \Sigma ^{ *+ } \)(1385) inK+p interactions at 32 GeV/c. The analysis is based on significantly larger statistics than previously available. A comparison is also made of invariantx-distributions ofK0/\(\bar K^0 \),\(\bar \Lambda \) and\(\bar \Xi ^ +\) and of\(\bar \Sigma ^{ *\pm } \)(1385) andK*+(892). These spectra exhibit regularities expected from the quark-recombination picture when it is assumed that the strange mesons and antibaryons are produced off the strange\(\bar s\)-valence-quark in the incidentK+ meson. Transverse momentum distributions are also presented forK*+(892) and\(\bar \Sigma ^{ *\pm } \)(1385) and found to be very similar. The results on strange antibaryon average multiplicities disagree strongly with a recent version of the additive quark model.

Production of Muon Pairs in the Continuum Region by 39.5-{GeV}/$c \pi^\pm$, $K^\pm$, $p$ and $\bar{p}$ Beams Incident on a Tungsten Target

Corden, M. ; Dowell, J.D. ; Garvey, J. ; et al.
Phys.Lett.B 96 (1980) 417-421, 1980.
Inspire Record 154577 DOI 10.17182/hepdata.27163

Inclusive dimuon production by 39.5 GeV/ c π ± , K ± , p and p¯ is described for masses greater than 2.0 GeV/ c 2 . The π − , π + and (π − − π + ) continuum cross-sections exceed the naive Drell-Yan predictions by a factor ∼2.4. The pion valence structure function has been measured and is consistent with a corresponding measurement at 200 GeV/ c .

Inclusive Production of Strangeness $S = \pm 1$ Vector and Tensor Resonances on $K^- P$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Arestov, Yu. ; Borovikov, A. ; Kozlovsky, E. ; et al.
Z.Phys.C 6 (1980) 101-108, 1980.
Inspire Record 154719 DOI 10.17182/hepdata.11053

We present final results on the inclusive production of the\(\bar K^{*0} (890)\),K*−(890),K*0(890),K*−(890),K*−(1420), and\(\bar K^{*0} (1420)\) resonances inK−p interactions at 32 GeV/c. Total cross sections and invariantx-distributions are determined. Inclusive cross sections of\(\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)\) amount to ≃4 mb each, of\(\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (1420)\) to ≃1 mb and ofK*0(890) to ≃0.8 mb. These values are in agreement with additive quark model predictions. All strangenessS=−1 resonances are predominantly produced in the forward hemisphere, the tensor mesons being more peripherally produced than the vector ones. The\(\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)\) density matrix elements andt-distributions are obtained. The unnatural spin-parity exchange contribution to inclusive\(\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)\) production amounts to ≳60% at |t|<0.4 GeV2 and decreases with increasing |t|. Whenever relevant, a comparison is also made with available data at other energies.

Measurement of Dimuon Production at the {ISR}

Antreasyan, D. ; Atwood, W. ; Battiston, R. ; et al.
Phys.Rev.Lett. 45 (1980) 863, 1980.
Inspire Record 153857 DOI 10.17182/hepdata.20656

Prompt dimuon production has been measured. Events with mass up to 25 GeV/c2 are observed, as well as the J and ϒ resonances. Cross sections are given for J and ϒ production. For the continuum, the scaling function F(τ) is measured at very small values of τ=ms covering the range 0.05<τ<0.20.
