Renormalizability of N=1\mathcal{N}=1 super Yang-Mills theory in Landau gauge with a Stueckelberg-like field

We construct a vector gauge invariant transverse field configuration $V^H$, consisting of the well-known superfield $V$ and of a Stueckelberg-like chiral superfield. The renormalizability of the Super Yang Mills action in the Landau gauge is analyzed in the presence of a gauge invariant mass term $m^2 \int dV \mathcal{M}(V^H)$, with $\mathcal{M}(V^H)$ a power series in $V^H$. Unlike the original Stueckelberg action, the resulting action turns out to be renormalizable to all orders.Comment: 19 page

Developing competency profiles of IT specialists based on semantic analysis of vacancies

The article focuses on applying Big Data processing methods and tools for creating specialists' competency profiles. It covers the approach developed to formulate the key competencies required for the IT vacancies. The first stage of the research includes carrying out a semantic analysis of the IT vacancies database. The second stage includes clustering of the results of semantic analysis and using them for building the map of the competencies of IT specialists. The modularity score reveals a significant isolation of the specialties in this area. The performed approach can be implemented in designing the professional standards and competency based education programs. © Published under licence by IOP Publishing Ltd
