Results are presented on inclusive production of ∑+(1385) and ∑−(1385) inK−p interactions at 110 GeV/c. The inclusive and topological cross sections have been estimated and compared with published results at lower energies. The inclusive cross section of ∑+(1385) seems to decrease with c.m. energy, while that of the ∑−(1385) is nearly constant. The mean charged multiplicity associate to Σ(1385) increases with c.m. energy. The ∑+(1385) is produced both in the target fragmentation region and in the central region where ∑−(1385) is predominantly produced in the central region. Approximately 16% of the Λ's stem from the decay of ∑±(1385) and the kinematic distributions of these Λ's are not very different from the inclusive Λ's.

Production of the F0 Meson in the Double Pomeron Exchange Reaction $p p \to p p \pi^+ \pi^-$ at $\sqrt{s}=62$-{GeV}

The Ames-Bologna-CERN-Dortmund-Heidelberg-Warsaw collaboration Breakstone, A. ; Campanini, R. ; Crawley, H.B. ; et al.

Data are presented for the exclusive reaction pp → pp π+ π− at$\sqrt s= 62GeV$ with two leading protons at large Feynman-x and a centrally produced π+;π− system. In this kinematical configuration one expects a substantial contribution from Double Pomeron Exchange, which is a potential source of glueballs. The experiment was performed at the CERN ISR using the Split Field Magnet spectrometer. In the mass range between 1,000 and 1,700 MeV/c2 the invariant mass distribution for the central π+;π− system exhibits a very significant signal for thef0(1270) and no other obvious resonant states.

$K^+$ Fragmentation and Prompt Kaon Production in $K^+ P$ Collisions at 70-{GeV}/c

De Wolf, E.A. ; Goldschmidt-Clermont, Y. ; Spyropoulou-Stassinaki, M. ; et al.

Z.Phys.C 31 (1986) 13-19, 1986.

Inspire Record 232414 DOI 10.17182/hepdata.15895

We present data on inclusive production ofK+ andKS0 mesons in a 70 GeV/cK+p experiment performed in BEBC filled withH2. Cross sections and inclusive Feynman-x distributions for identifiedK+'s andKS0's are presented. The spectra of “prompt” non-diffractiveKS0 are determined by subtraction of the decay products of prominent resonances and diffractive contributions. These data, contrary to the overall inclusive spectra, allow to differentiate between some fragmentation models for soft hadron-hadron interactions.
