We present a systematic analysis of the production of K ∗+ (892) and Δ ++ (1236) resonances in the K + p → K 0 p π + reaction at 5, 8.25 and 16 GeV/ c . We have measured total cross sections, differential cross sections, density matrix elements and examined resonance production mechanisms in terms of the exchange of states with definite naturality. Some results on the reaction K + p → K ∗+ (1420) p are also given.

STUDY OF D (1285) ---> K+ K- pi0 DECAY

JETP Lett. 39 (1984) 115, 1984.
Inspire Record 195747 DOI 10.17182/hepdata.41100

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.

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

Inspire Record 201523 DOI 10.17182/hepdata.39601

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.

Measurement of $\phi$ Meson Radiative Decays at the Storage Ring Vepp-2m With the Neutral Detector

Results of the first experiments with the Neutral Detector at the electron-positron storage ring VEPP-2M are presented. Branching ratios of the ø-meson radiative decays have been measured: B ( ø → ηγ )=(1.30±0.06)%, B ( ø → π 0 γ )=(0.130±0.013)%, their accuracy being several times higher than the world average. The width ratio is Γ(ø→ηγ) Γ(ø→π 0 γ)=(10±1) . Using the abovementioned quantities, the ω − ø mixing angle θ v =(38.3±0.2) ° , as well as the ratio between the effective magnetic moments of the s- and u-quarks, μ s μ u =(0.57±0.03) have been calculated.
