Inverse problem of the event reconstruction in the LORD experiment using the signal speсtrum information
Аннотация
Using the modified random search method, the solution of the inverse problem of reconstructing events in the LORDlunar experiment is considered using the signal spectral analysis, where the total frequency band of 200–400 MHz is divided into four equal frequency bands. Additional information about the signal will allows one to achieve a higher accuracy in the solution of the inverse problem.



Will protons become gray at 13 TeV and 100 TeV?
Аннотация
It is shown that the regime of pp-interactions at 7 TeV is a critical one. The LHC data about elastic pp-scattering at 7 and 8 TeV are used to get some information about both elastic and inelastic profiles of pp-collisions. They are discussed in the context of two phenomenological models which intend to describe the high energy pp-data with high accuracy. Some predictions following from these models for an LHC energy of 13 TeV and for an energy of 95 TeV of the newly proposed collider are discussed. It is claimed that the center of the inelastic interaction region will become less dark with an increase of energy albeit very slowly.



Magnetopause charging and transfer of momentum and energy into magnetosphere
Аннотация
The theory of charged current sheets is compared with plasma data of Prognoz-8, Interball-1, Polar, and Cluster satellites. The possibility of momentum and energy transfer into the magnetosphere, irrespective of magnetic field line reconnection, as a specific dynamo effect, is shown. This relates statistical properties of the turbulent boundary layers with the character of the transfer through thin boundaries.



Entropic and information inequalities in the tomographic probability description of spin-1 particles



Luminescence of tungsten centers in zinc selenide
Аннотация
Luminescence spectra of W centers in ZnSe are studied. Radiative d–d transitions are identified by the Tanabe–Sugano diagram of the crystal field theory. It is found that the type of electronic transitions changes with a significant change in spectral characteristics of impurity radiation during the transition fromthe 3d- to 5d-electronic systemof impurity centers in the crystals under study.



Hypothesis of friedmons as dark matter particles and hypothesis of initial cosmological constant decay
Аннотация
Hypothesis of friedmons as dark matter particles is proposed. Friedmons are stable particles with a mass of billion nucleon masses. These particles correspond to the not yet been discovered exact symmetry group dual to the SU(2) group: for the Standard model symmetries and dual symmetries, the roles of exact and broken symmetries and corresponding stable and unstable particles change places. The hypothesis of the decay of the primordial de Sitter vacuum of the Planck density to an asymptotic state of the expanding Universe with de Sitter vacuum of the observed critical density is proposed. The T -duality and S-duality hypotheses relating subgroups SU(3)×SU(2)×U(1) and dual subgroups S˜Ũ(3)× S˜Ũ(2) × ˜Ũ(1) with decay of the primordial symmetry group E(8) × ˜Ẽ(8) are proposed. In particular, these dualities relate the minimum Planck length 10−13 cm to the primordial curvature radius 10−13 cmof theMetagalaxy of the Planck density and its modern curvature radius of 1028 cm. That is, the probable relation of the Planck mass to the Metagalaxy mass of 1061 Planck masses is indicated.



On the possible separation of the phase enriched with Nb in superconducting intermetallic Nb3Sn irradiated with fast protons
Аннотация
The results of the study of magnetization and dynamic magnetic susceptibility are correlated with changes in the microstructure of superconducting intermetallic Nb3Sn plates irradiated at the Kurchatov Institute cyclotron with fast protons with an energy of 12.8 MeV to a fluence of 1 · 1018 cm−2. The dependence of the superconducting transition temperature on the total irradiation dose is determined. For one of the samples, the dynamic magnetic susceptibility exhibits several steps corresponding to superconducting transitions at different temperatures. It is assumed that a Nb-enriched phase is separated in the region of maximum radiation damages. A microstructural analysis shows the appearance of randomly oriented Nb-enriched regions from 0.1 to 0.5 μm in size.
