[en] Interest in the Atiyah-Singer index theorem and the closely related Atiyah-Bott-Lefshetz formula has increased sharply in recent years. This is explained by the discovery of the connection of the index theorem and Lefshetz type formulas with supersymmetric quantum theories. In this work, a brief survey of the directions in which the Atiyah-Bott theorem has been generalized are given. Elliptic complexes on a manifold with boundary whose differentials are Boutet de Monvel operators are studied. An Atiyah-Bott-Lefschetz type formula is obtained for such complexes. 50 refs., 1 fig

[en] The major purpose of the muon identifier is a reliable isolation of muons produced in e⁺e^- annihilation in I resonances energy region, with a considerable number of hadrons. The muon identifier for the detector KEDR consists of sensitive double layers of streamer tubes placed after hadron absorber layers. System comprises 8 barrel octants and 2 endcaps. The barrel has 4 sensitive layers and the endcaps have only the outer one. In this paper only sensitive elements are under discussion. The physical parameters of the identifier can be found elsewhere. Streamer tubes are assembled in modules. Total number of modules is 120 in the barrel and 24 in the endcaps. Total number of tubes is 3136 in the barrel and 768 in the endcaps

[en] The results of the BELLE barrel calorimeter prototype test with the tagged photon beam are presented. The prototype consisted of 36 CsI(Tl) counters with the same readout system as the BELLE calorimeter. The measurements were carried out at the VEPP-4 collider with the tagged photon beam provided by the ROKK-1M facility. The energy resolution for photons was measured in the energy range 40-800 MeV. The results are in good agreement with the Monte-Carlo simulation. (orig.)

[en] The general purpose detector CMD-2 at the VEPP-2M electron-positron collider at Novosibirsk has collected about 11 pb^-1 of integrated luminosity in the center-of-mass energy range from 0.36 up to 1.38 GeV. Data in the ρ-meson energy range from 0.61 to 0.96 GeV have been analysed and preliminary results on the e⁺e^-→π⁺π^- cross-section in this energy range are presented. copyright 1998 American Institute of Physics

[en] KEDR is a general-purpose detector for experiments at the VEPP-4M e⁺e^--collider in the energy range 2E=2.0-12 GeV. All detector subsystems (except the aerogel Cherenkov counters) have been installed into the detector at VEPP-4M. Some preliminary data have been taken in the energy region of the J/Ψ meson. The tuning of the detector and the VEPP-4M collider is in progress. Preliminary results on the detector performance are presented. The future experimental program for the KEDR detector is discussed
