    A new precise measurements of spin density matrix element ρ00\rho_{00} of K(892)±K^*(892)^{\pm} mesons produced inclusively in neutron-carbon interactions at \~60 GeV have been carried out in the EXCHARM experiment at the Serpukhov accelerator. The values of ρ00\rho_{00} obtained in the transversity frame are 0.424±0.011(stat)±0.018(sys)0.424\pm0.011(stat)\pm0.018(sys) for K(892)+K^*(892)^+ and 0.393±0.025(stat)±0.018(sys)0.393\pm0.025(stat)\pm0.018(sys) for K(892)K^*(892)^-. Significant PTP_T dependence of ρ00\rho_{00} has been observed in K(892)+K^*(892)^+ production.Comment: 8 pages, LaTeX, 3 eps figure

    ხარაგაულის რაიონში ხელსაყრელ პირობებთან ერთად ადგილი აქვს საშიშ ჰიდრომეტეოროლოგიურ და გლაციოლოგიურ მოვლენეებს. დაკვირვების მიზნით პირადი სახსრებით გაიხსნა ჰიდროლოგიური საგუშაგო მდ. ყორნებაზე და მეტეოროლოგიური საგუშაგო სოფ. ღვერკში. შეგროვდა 3 წლის მონაცემები. სისტემატურად მიმდინარეობს მიღებული მასალების დამუშავება. ამან საშუალება მოგვცა დაგვეზუსტებინა ბუნებრივი მოვლენების განვითარების კანონზომიერებანი, რათა გამოვყოთ საშიში უბნები, შევიმუშავოთ საჭირო ადაპტაციური ღონისძიებები და სხვა.In district of Kharagauli, with profitable conditions take place the horror hydrometeorological and occurrences. By observation purpose by personal guard. In the village Gverki. Three yearsZ datas are collected. Systemically currents received materials work. That gave us a chance to precise the principles of natural occurrences development, for separate the horror district, working out needful adapted measures and other.В Харагаульском раионе имеют место опасные гидрометеорологические и глациологические явления. Для наблюдений на их режиме открыт гидрологический створ на реке Корнеба и метеорологический пост в селе Гверки. Собраны трёхлетние матерялы наблюдений; Систематический провадится обработка и анализ их. Это дало возможность уточнить закономерность развития природных явлений, выделить опасные участы и разработать нужные адаптационные мероприятия и др

    Interference Correlations of Hyperons in Neutron-Carbon Interactions

    No full text
    The interference correlations of \Lambda-hyperon pairs produced on the carbon target by 20-70 GeV neutrons have been investigated with the EXCHARM spectrometer. Destructive correlations at low relative 4-momenta are observed for \Lambda\Lambda-pairs. No correlations of this type are observed for \Lambda\bar{\Lambda}. Comparison with the corresponding data on meson correlations shows a decrease of production area sizes with an increase of particle masses
