An analysis of theA-dependence of the target-diffractive cross-section is presented. Data on thet-dependence of the cross section are fitted in the usual exponential form. The mean multiplicity of negative particles produced diffractively is found not to be sensitive to the nuclear mass. TheA-dependence of the emitted proton multiplicity and the angular distributions of the produced charged particles suggest re-scattering of the emitted particles on other nucleons of the nucleus. All these facts are compared with results obtained by Monte-Carlo simulation according to a two-component Dual Parton Model.

The production of$\bar D$ mesons in neutroncarbon interactions at 40–70 GeV/c has been investigated. The$\bar D$ mesons were detected via the hadronic decay modes$\bar D^0\to K^{* + } (892)\pi ^ -$ andD−→K*+(892)π−π−. In the kinematical regionxF>0.5 andpT<1 GeV/c the following inclusive cross sections were measured:$\sigma _{\bar D^0 }= (28 \pm 14)\mu b$ and$\sigma _{D^ -}= (28 \pm 13)\mu b$ per carbon nucleus. The invariant longitudinal momentum spectra can be described by (1−x)N with$N_{\bar D^0 }= 1.1 \pm 0.5 \pm 0.4$ and$N_{D^ -}= 0.8 \pm 0.4 \pm 0.4$ The transverse momentum spectra were parametrized by exp (−BpT2) with$B_{\bar D^0 }= (1.2_{ - 0.9}^{ + 1.1} )({{GeV} \mathord{\left/ {\vphantom {{GeV} c}} \right. \kern-\nulldelimiterspace} c})^{ - 2} $ and$B_{D^ -}= (1.8_{ - 1.0}^{ + 1.3} )({{GeV} \mathord{\left/ {\vphantom {{GeV} c}} \right. \kern-\nulldelimiterspace} c})^{ - 2} $.

Observation and Study of a Narrow State in a $\Sigma^-$ (1385) $K^+$ System

New data on the observation and study of a narrow resonance decaying intoΣ−(1,385)K+ have been obtained. The mass of the resonance is (1,956−6+8) MeV/c2, and its width is (27±15) MeV/c2. The resonance is produced in the diffraction dissociation of neutrons on quasi-free nucleons of carbon nuclei. The slope parameter of the differential cross section inPT2 is (9.9±3.0) (GeV/c)−2. The cross section times the branching ratio is (0.22±0.04) μb per nucleon. The resonance has one of the natural spinparities: 5/2+, 7/2− and so on.
