The non-Universal U(1) gauge extended μνSSM: anomalies cancellation and singular phenomenology
Journal of High Energy Physics, 2018 So far the most sophisticated experiments have shown no trace of new physics at the TeV scale. Consequently, new models with unexplored parameter regions are necessary to explain current results, re-examine the existing data, and propose new experiments.

LHC-7 supersymmetry search interpretation within the pMSSM [PDF]
, 2012 The ATLAS collaboration published supersymmetry limits based on up to about 4.7 \ifb data collected over the year 2011 from LHC runs at 7 TeV. These were mainly interpreted within restricted, particular or simplified models for supersymmetry breaking schemes or scenarios.

Journal of High Energy Physics, 2018 Recently, a new minimal extension of the Standard Model has been proposed, where a spontaneously broken, flavor-dependent global U(1) symmetry is introduced.

Naturalness and the Status of Supersymmetry [PDF]
, 2013 For decades, the unnaturalness of the weak scale has been the dominant problem motivating new particle physics, and weak-scale supersymmetry has been the dominant proposed solution. This paradigm is now being challenged by a wealth of experimental data.

On a reinterpretation of the Higgs field in supersymmetry and a proposal for new quarks
Physics Letters B, 2017 In the framework of supersymmetry, when R-parity is violated the Higgs doublet superfield Hd can be interpreted as another doublet of leptons, since all of them have the same quantum numbers. Thus Higgs scalars are sleptons and Higgsinos are leptons.

Supersymmetry Phenomenology With a Broad Brush [PDF]
arXiv, 1996 These lectures provide an introduction to supersymmetry phenomenology. They include an overview of the Minimal Supersymmetric Standard Model. The notion of soft breaking is explained, constraints on the standard soft breaking parameters are reviewed, and the standard ansatz of universal soft masses is discussed.

Magnifying the ATLAS stealth stop splinter: impact of spin correlations and finite widths
Journal of High Energy Physics, 2018 In this paper, we recast a “stealth stop” search in the notoriously difficult region of the stop-neutralino Simplified Model parameter space for which mt˜1−mχ˜10≃mt $$ m\left({\tilde{t}}_1\right)-m\left({\tilde{\upchi}}_1^0\right)\simeq {m}_t $$.

Spontaneous Scherk-Schwarz supersymmetry breaking and radion stabilization [PDF]
, 2004 In this talk I review the issues of supersymmetry breaking and radion stabilization in a five dimensional theory compactified on the Z_2 orbifold. Supersymmetry breaking by Scherk-Schwarz boundary conditions is interpreted as spontaneous breaking of local supersymmetry by the Hosotani mechanism.

The $μ$-Parameter of Supersymmetry [PDF]
arXiv, 1999 The Higgsino mass, or equivalently the $\mu$-parameter, plays an essential role in determining the phenomenology of any supersymmetric model. Particularly, the size of the supersymmetry conserving mu-parameter must be correlated with the size of the soft supersymmetry breaking parameters.
