Results on the study of D(1285)→K + K − π 0 -decay are presented. The K + K − effective mass spectrum is measured with statistics which are by an order of magnitude higher than in the previous data. From the analysis of the differential spectrum d N d M KK (in the framework of the δ-dominance model) the δ-meson effective width is Γ δ >180MeV/ c 2 at √ s =1 GeV/ c 2 , which means a strong coupling of the δ-meson with hadrons.

Properties of Multiplicity Distributions in $\nu A$ and $\bar{\nu}A$ Interactions at $E_{\nu/\bar{\nu}}\le 30$-{GeV}

We present data on the multiplicity structure of inclusive charged hadron production in charged current neutrino and antineutrino freon interactions in the energy range 3–30 GeV resulting from an experiment with the bubble chamber SKAT. Average multiplicities, dispersions and correlation coefficients are investigated. Furthermore, KNO-scaling is studied and average net charges are calculated in different kinematical regions. Our data are compared with results from$\begin{array}{*{20}c}{( - )}\\v\\ \end{array} $-interactions on an isoscalar target of “free” nucleons to study the influence of nuclear effects.

Muon Pairs and Upper Limit for $\Upsilon$ Production by 280-{GeV} Muons

Bollini, D. ; Frabetti, P.L. ; Heiman, G. ; et al.

The high mass μ + μ − pairs produced by 280 GeV μ + on a carbon target are studied in a search for the Y production. The high mass continuum in the region 2–18 GeV is interpreted in terms of QED pair production and of μ pairs originating from the decay of hidden and open charm particles as well as of hadrons ( π , K) from deep inelastic interactions. The upper limit for the upsilon production by muons is found to be, at the 90% confidence level, σ γ ·(γ→μ + μ − )<13·10 −39 cm 2 /nucleon.
