Collider phenomenology of Higgs bosons in Left-Right symmetric Randall-Sundrum models

We investigate the collider phenomenology of a left-right symmetric RandallSundrum model with fermions and gauge bosons in the bulk. We find that the model is allowed by precision electroweak data as long as the ratio of the (unwarped) Higgs vev to the curvature scale is v/k ≤ 1/4. In that region there can be substantial modifications to the Higgs properties. In particular, the couplings to WW ...

Phenomenology of the two Higgs doublet sector of a quark-lepton symmetric model.

In the simplest examples of models with a discrete quark-lepton symmetry, an electroweak symmetry breaking sector with more than one Higgs doublet is necessary to obtain the correct mass relations between quarks and leptons. A two Higgs doublet model version has flavour-nonconserving Yukawa couplings, which are proportional to the masses of the quark-lepton symmetric partners of the fermions. W...

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...
