Investigations of electroweak symmetry breaking mechanism for Higgs boson decays into four fermions

Models with extended Higgs boson sectors are of prime importance for investigating the mechanism of electroweak symmetry breaking for Higgs decays into four fermions and for Higgs-production in association with a vector bosons. In the framework of the Two-Higgs-Doublet Model using two scenarios obtained from the experimental measurements we presented next-to-leading-order results on the four-fermion decays of light CP-even Higgs boson, $h \rightarrow 4f$. With the help of Monte Carlo program Prophecy 4f 3.0, we calculated the values $\Gamma= \Gamma_{EW} /\left(\Gamma_{EW}+\Gamma_{SM}\right)$ and $\Gamma= \Gamma_{EW+QCD} /\left(\Gamma_{EW+QCD}+\Gamma_{SM}\right)$ for Higgs boson decay channels $H \rightarrow \nu_{\mu} \overline{\mu} e \overline{\nu_e}$, $\mu \overline{\mu} e \overline{e}$, $e \overline{e} e \overline{e}$. We didn't find significant difference when accounting QCD corrections to EW processes in the decay modes of Higgs boson. Using computer programs Pythia 8.2 and FeynHiggs we calculated the following values: $\sigma(VBH)BR(H\rightarrow ZZ)$ and $\sigma(VBF)BR(H \rightarrow WW)$ for VBF production processes, $\sigma(ggH)BR(H \rightarrow WW)$ and $\sigma(ggH)BR(H \rightarrow ZZ)$ for gluon fusion production process at 13 and 14 TeV and found good agreement with experimental data.Comment: 4 pages, 2 figure

Studying the resonance production cross-section of the heavy vectors within Heavy Vector Triplet model

In the context of TeV-scale extensions of the Standard Model both the experimental searches and the construction of phenomenological models for the new heavy bosons searches are used by us. Heavy particles predicted by a the Simplified Model constructed to describe only the on-shell resonance, have to be compared with LHC data. Heavy bosons have certain properties that can be calculated within the Heavy Vector Triplet model using the MadGraph computer program. We have calculated the production cross sections of heavy particles using the experimental constraints in the parameter space ($c_H$, $c_F$) imposed on the benchmark scenario. The nature of the functional dependence of the cross section at the basic parameters of the model on the mass of the new boson, as well as the mechanism for the heavy particle production is studied.Comment: 9 pages, 9 figure

Landscape phage, phage display, stripped phage, biosensors, detection, affinity reagent, nanotechnology, Salmonella typhimurium, Bacillus anthracis

Filamentous phage, such as fd used in this study, are thread-shaped bacterial viruses. Their outer coat is a tube formed by thousands equal copies of the major coat protein pVIII. We constructed libraries of random peptides fused to all pVIII domains and selected phages that act as probes specific for a panel of test antigens and biological threat agents. Because the viral carrier is infective, phage borne bio-selective probes can be cloned individually and propagated indefinitely without needs of their chemical synthesis or reconstructing. We demonstrated the feasibility of using landscape phages and their stripped fusion proteins as new bioselective materials that combine unique characteristics of affinity reagents and self assembling membrane proteins. Biorecognition layers fabricated from phage-derived probes bind biological agents and generate detectable signals. The performance of phage-derived materials as biorecognition films was illustrated by detection of streptavidin-coated beads, Bacillus anthracis spores and Salmonella typhimurium cells. With further refinement, the phage-derived analytical platforms for detecting and monitoring of numerous threat agents may be developed, since the biodetector films may be obtained from landscape phages selected against any bacteria, virus or toxin. As elements of field-use detectors, they are superior to antibodies, since they are inexpensive, highly specific and strong binders, resistant to high temperatures and environmental stresses.Comment: Submitted on behalf of TIMA Editions (http://irevues.inist.fr/tima-editions

ДО ПРОБЛЕМИ ХАРАКТЕРИСТИКИ ФОРМ ОЦІНЮВАННЯ ЕФЕКТИВНОСТІ ДІЯЛЬНОСТІ СУДІВ

It has been proved that evaluation is an extremely important tool for controlling the activities of courts. Its special significance is that it allows to obtain content and fundamental data on the level of quality, efficiency and effectiveness of the court activities without direct interference into its activities on administration of justice. That is, by providing relevant information on the activities of the court, the assessment contributes to the observance of its independence as a judicial agency. It has been determined that due to the evaluation it is possible not only to establish the degree of conformity of the qualitative and quantitative indicators of the court’s activities with the established legal requirements and public expectations and requests, but also to detect the problematic aspects of the courts activities; to provide a more rational and effective approach to allocating resources, including personnel, to specify, prioritize and improve the work of the court and judges more precisely and clearly. At the same time it has been noted that the assessment concerns only the organizational and managerial aspects of the work of the court and does not provide the verification of the efficiency and effectiveness directly of the just activities of judges of the court (courts). It has been established that the evaluation of the court activity is carried out mainly in the forms of questioning (external and internal) and the study of reporting and other documents containing statistics on the work of courts. Their analysis has been accomplished; and propositions for their improvement have been provided. It has been stressed that the existing system of assessing the work of the court is very informative and contains almost all indicators, forms and methods necessary for obtaining reliable data about the activity of judicial agencies, including those that administer justice. At the same time, the author has noted that such a system, even its basic components, are not mandatory, but only recommended for the application, that is why the mechanism of the studied evaluation is often not properly implemented in practice.Доведено, що оцінювання виступає надзвичайно важливим інструментом перевірки якості, ефективності та результативності діяльності судів.

Formation of J-aggregates of Thiamonomethincyanine Dyes in the Presence of CdTe Nanoparticles

The conditions of formation of J-aggregates for three types of thiamonomethincyanine dyes, whose structure is differed by end groups, are studied depending on their concentration and type of interaction with CdTe nanoparticles with size of about 3 nm in aqueous dispersions. The influence of dye structure on the efficiency of formation of J-aggregates in solutions and in films was found. It was found that quantum dots (QDs) of CdTe stabilized by thioglycolic acid can adsorb J-aggregates of the dye molecules on their surface. It was shown for the first time that the hybrid structure of dye-CdTe can be formed through the interaction of negatively charged dye molecules and negatively charged surface of the QDs through the formation of neutral aggregates. It was not found any processes of energy transfer from dye to the particles of CdTe neither for the dimer - CdTe system nor for the J-aggregates – CdTe system.

Сутність і значення адміністративних процедур у діяльності судів

The approaches of scholars to the definition of the concept and characteristics of the peculiarities of administrative procedures have been analyzed; the features of administrative procedures in the activity of courts have been provided and their significance has been revealed; the stages of administrative procedures in the activity of the courts have been established. It has been established that administrative procedures in the activity of the courts are a consistent procedure of administrative or organizational and regulatory activities of the court, judge or authorized person determined by the current administrative legislation for the adoption of a specific decision in a case or performance of management function. Accordingly, the features of administrative procedures in the activities of the courts are that they: are an expression of administrative activities of the authorized subject; are the realization of the competence of the authorized subject in relation to the implementation of the respective management functions; have a clearly defined form of external expression of state administration; have a standardized procedure for the implementation and application; provide an opportunity to determine / confirm the status of an authorized person for the implementation of the management function; have an individual orientation. It has been proved that the significance of administrative procedures in the activities of the courts is that: to organizationally provide the activity of the courts; to ensure the rights, freedoms and legitimate interests of individuals and legal entities; to create a unified approach / algorithm of actions of authorized persons of a court for taking a management decision; to ensure publicity of the activity of the courts in the process of adopting and implementing organizational and administrative or managerial decisions; to enable powerless subjects to understand the procedure how they can exercise their right or how they will control the fulfillment of their duties; in the manner prescribed by law, to ensure compulsory execution of judgments; to ensure the efficiency of the court’s activity in accordance with international norms and standards.Проаналізовано підходи вчених до визначення поняття та характеристики особливостей адміністративних процедур, подано ознаки адміністративних процедур у діяльності судів і розкрито їх значення, встановлено стадії адміністративних процедур у діяльності судів
