Experiment Pamir-4: analysis of superfamily with halo of electromagnetic nature detected in deep XEC
AbstractAbstract
[en] The family Pb2-11 was detected in the multilayer lead XEC with total thickness of 100 c.u. exposed at the Pamirs. Each lead layer was 1 cm thick, the first registering layer being located under 2 cm of Pb(= 4 c.u.). The family comprised a narrow group of gamma-rays which near the maximum of cascade development (= 14 c.u.) produced a dark spot of optical density D approx. .4 over area S = 25 sq.mm. The narrow group of gamma-rays was traced up to the 14th layer corresponding to 30 c.u. Deeper in the chamber, for the space of 70 c.u., no hadron cascade was observed. Thus, a pure electromagnetic halo could be assumed. Preliminary results of the analysis of the family Pb2-11 are presented. The methods of estimation of the energy of the primary particle and the height of nuclear interaction responsible for the observed halo are considered in more detail

AbstractAbstract
[en] Performances of ten detectors for the recording of cosmic neutrinos resulted from gravitational star collapse in the Galaxy are presented. It is shown that for effective search for star collapse in the Galaxy it is necessary to use not less than three independent detectors. Such collapses have not been recorded by these ten detectors for last ten years

AbstractAbstract
[en] Fluxes of atmospheric neutrinos with high energies are calculated with taking into account the muon data on the charm generation obtained in cosmic rays. An empirical model of charmed particle generation in the all interval of considered energies in used. Ratios of differential fluxes of electron and muon atmospheric neutrinos, generated in charmed particle decays, to corresponding fluxes, generated in pion and kaon decays, are presented

AbstractAbstract
[en] Experimental data, obtained when searching neutrino radiation from gravitational collapse of stars are discussed. The following reactions are used for neutrino detection in experiments: ν-tildee+p→n+e+ and ν+e-→ν+e-. Characteristics of four detectors, used during flare of Supernovae star on February, 23, 1987: Baksan underground scintillation telescope, Soviet-Italian liquid scintillation detector LSD, Cherenkov detector K2 (Japan-USA) and Cherenkov detector IMB(USA). Analysis of experiments showed that effects in each of four detectors satisfied or at least didn't disagree with conditions of mentioned reaction detection. Many problems should be solved when interpreting the whole body of results of neutrino detectors: two-stage mechanism of collapse, different angular distributions of K2 and IBM etc. The main problem lies in the fact, that measured enrgy fluxes in neutrino radiation exceed many times the same ones, permissible from the view point of modern astrophysical concepts

AbstractAbstract
[en] Medium energy neutrinos from decays of pions and kaons produced in interactions of protons, accelerated in solar flares, can come to the Earth and be detected with neutrino telescopes. Estimations of fluxes of these neutrinos are made in the work. Solar flare neutrinos as a possible source for experiments on searching for neutrino oscillations is discussed
