Observation of an anomaly in the angular distribution of cumulative hadrons near the backward direction

The angular distributions of secondary pions, protons, and deuterons originating from π^?Pb interactions at an incident-pion momentum of 5 GeV/c was determined in a new run of measurements relying on track reconstruction. While showing a decrease over a large angular interval with increasing emission angle, the yield of cumulative particles of each species was found to be anomalously large near the backward direction.     

Is it possible to estimate the Higgs mass from the CMB power spectrum?

General Relativity and Standard Model are considered as a theory of dynamical scale symmetry with definite initial data compatible with the accepted Higgs mechanism. In this theory the Early Universe behaves like a factory of electroweak bosons and Higgs scalars, and it gives a possibility to identify three peaks in the Cosmic Microwave Background power spectrum with the contributions of photonic decays and annihilation processes of primordial Higgs, W and Z bosons in agreement with the QED coupling constant, Weinberg’s angle, and Higgs’ particle mass of about 118 GeV. The text was submitted by the authors in English.     

Solution of the Boltzmann equation for unsteady flows with shock waves in narrow channels

Unsteady rarefied gas flows in narrow channels accompanied by shock wave formation and propagation were studied by solving the Boltzmann kinetic equation. The formation of a shock wave from an initial discontinuity of gas parameters, its propagation, damping, and reflection from the channel end face were analyzed. The Boltzmann equation was solved using finite differences. The collision integral was calculated on a fixed velocity grid by a conservative projection method. A detector of shock wave position was developed to keep track of the wave front. Parallel computations were implemented on a cluster of computers with the use of the MPI technology. Plots of shock wave damping and detailed flow fields are presented.

Characteristic features of the velocity dispersion of surface acoustic waves in anisotropic coated solids

Basic patterns of the velocity versus wavenumber dispersion of the surface waves in solids coated by a relatively light or dense, "slow" or "fast" layer are discussed in the general case of an arbitrary anisotropy of substrate and coating materials. The onset of the subsonic wave branch, characterized by either a speeding or a slowing trend, is examined. Competitive tendencies, which pertain to the low-frequency dispersion in the case of dense "fast" layer, are revealed.     

The contributions from different mechanisms of motion of domain boundaries to the effective permittivity of triglycine sulfate crystals in moderate low-and infralow-frequency fields

A study of the special features of contribution of domain boundaries to the effective permittivity ? _eff ^* of a TGS crystal is made in electric fields of various frequencies and in a wide temperature range of the polar phase, up to the phase transition temperature. In considering the experimental data obtained, we classify the defects into three types depending on their interaction strength with the domain boundaries. Using the approach developed, we explain the frequency and temperature dependences of the contributions from the hysteretic and relaxation mechanisms of motion of the domain boundaries to ? _eff ^*
