Dark matter phenomenology of SM and enlarged Higgs sectors extended with vector-like leptons

We will investigate the scenario in which the Standard Model (SM) Higgs sector and its two-doublet extension (called the Two Higgs Doublet Model or 2HDM) are the "portal" for the interactions between the Standard Model and a fermionic Dark Matter (DM) candidate. The latter is the lightest stable neutral particle of a family of vector-like leptons (VLLs). We will provide an extensive overview of...

Growing Hierarchical Sectors on Sectors

Self-organizing maps are widely used in visual data mining. This paper proposes a new visualization approach for GHSOM algorithm, a hierarchical variant of SOM. The method is based on pie charts. That improves the visualization in hierarchical data structures making possible to extract all the existing relationships among the attributes of the neurons at any hierarchy level. The methodology is ...

Phenomenology and Post-Modernity

Qualitative research methodology: phenomenology

There are two qualitative and quantitative research paradigms in the methodological debates. Phenomenological approach is one of the most important methods in the qualitative researches. ‎Depending on researcher’s view on study phenomenon, this approach is divided into two main ‎methods of descriptive and interpretive. Despite the many similarities between the two methods, ‎th...

H ± phenomenology

In supersymmetric models with explicit breaking of R-parity the lightest supersymmetric particle (LSP) may be the lightest stau, τ̃1. Such a scenario would provide a clear sign of R-parity violating SUSY, although its phenomenology may resemble that of a charged Higgs boson, H. We discuss various ways of distinguishing a LSP τ̃1 from H ± at future colliders, and address the case of τ̃1 mimicking t...
