Andreev Vasili V., Pankov A.A. Discrimination between Z'-boson and anomalous gauge couplings effects in at ILC

We discuss the foreseeable sensitivity to Z' of -pair production cross sections at the International Linear Collider (ILC), especially as regards the potential of distinguishing observable effects of the Z' from the analogous ones due to competitor models with anomalous trilinear gauge couplings (AGC) that can lead to the same or similar new physics experimental signatures at the ILC. The model independent analysis of the Z' effects in the process allows to differentiate the full class of vector Z' models (except sequential SM (SSM)-like models) from those with anomalous trilinear gauge couplings. Results of model dependent analysis of a specific Z' are expressed in terms of discovery and identification reaches on the ZZ' mixing angle and the Z' mass.

Keywords: Z'-boson, anomalous gauge couplings, ZZ' mixing.

Anisimova A.E. Acoustooptical diognostics of ultrasonic Lamb waves of high-orders

The acoustooptical Bragg diffraction of light by the Lambs waves of higher order of a plate from isotropic solid material is investigated. It is shown that acoustooptical modulation deep is reached for diffraction of transmitted waves of the first order. Lambs modes are stated to be separately diagnosed by means of the acoustooptical method.

Keywords: Lambs waves, acoustooptical diffraction, amplitude modulation, coefficients of reflection and transmission.

Kovtun-Kuszhel V.A., Dynich R.A., Ponyavina A.N. Localization and scattering of electromagnetic waves in ordered arrays of finite cylinders

We considered a high-ordered array of a finite number of circular cylinders characterized by a defined length and oriented perpendicu-larly to a planar substrate (so called multimers). On the base of the volume integral equation formalism we studied both straight and inverse dielectric systems with a honeycomb structure. The scattering direction diagrams and a field distribution into/near the cylinders included into a multimer were analyzed at different cylinder and multimer sizes and for a number of materials under condition of incident light directed along a pore axis.

Keywords: space-ordered cylinders, direction diagrams, near-field distribution.

Sidsky V.V., Semchenko A.V., Gaishun V.E., Kolo V.V.s, Turtsevich A.S., Soroka S.A., Asadchiy A.N. Ferroelectric properties of SBT-films synthesized by sol-gel method

This paper examines the relationship between the ferroelectric and structural properties of the films of Sr1+yBi2+xTa2O9, synthesized by the sol-gel method. It is shown that the variation of the stoichiometric ratio between the source components included in the structural formula of SBT-material leads to a structural change, and therefore the ferroelectric properties of SBT-layers. As we approach the region of instability of the system as the value of the Curie point decreases.

Keywords: sol-gel, SBT-films, hysteresis loop, dielectric constant, Curie temperature.

Eryomina A.R. Insensibility of stationary distribution of queueing network with multimode strategies states when parameters of the servicing and switching processes are dependent on unit state

The open queueing network with polytypic demands is considered in the article. The single line units can work in some strategies. The quantity of the work which are necessary for servicing of demand and for switching from one strategy to another are random variables with arbitrary distribution function. The parameters of servicing and switching processes are dependent on the general unit state. It was proved that stationary distribution is invariant in relation to functional form of distribution of works quantities which are necessary for servicing of demands and switching of strategies, on condition that first moments are fast.

Keywords: queueing network, stationary distribution, multimode service, insensibility.
