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 $$ m\left({\tilde{t}}_1\right)-m\left({\tilde{\upchi}}_1^0\right)\simeq {m}_t $$.

Phenomenological indications of the scale of supersymmetry [PDF]

Journal of High Energy Physics, 2006
Electroweak precision measurements can provide indirect information about the possible scale of supersymmetry already at the present level of accuracy. We update the present-day sensitivities of precision data using the new experimental top-quark mass, m_t = 172.7 \pm 2.9 GeV, within the constrained minimal supersymmetric extension of the Standard ...

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.

The light sgoldstino phenomenology: explanations for the muon (g − 2) deviation and KOTO anomaly

Journal of High Energy Physics, 2020
In this work, we study the long-standing experimental anomaly in muon (g −2) and also recent anomalous excess in K L → π 0 + v v ¯ $$ {K}_L\to {\pi}^0+v\overline{v} $$ at the J-PARC KOTO experiment with sgoldstino.

Pole mass determination in presence of heavy particles

Journal of High Energy Physics, 2019
We investigate the determination of the Higgs-boson propagator poles in the MSSM. Based upon earlier works, we point out that in case of a large hierarchy between the electroweak scale and one or more SUSY masses a numerical determination with DR Higgs ...

Exploring charge and color breaking vacuum in non-holomorphic MSSM

Journal of High Energy Physics, 2017
Non-Holomorphic MSSM (NHSSM) shows various promising features that are not easily obtained in MSSM. However, the additional Non-Holomorphic (NH) trilinear interactions that attribute to the interesting phenomenological features, also modify the effective

Data-driven analysis of a SUSY GUT of flavour

Journal of High Energy Physics, 2022
We present a data-driven analysis of a concrete Supersymmetric (SUSY) Grand Unified Theory (GUT) of flavour, based on SU(5) × S 4, which predicts charged fermion and neutrino mass and mixing, and where the mass matrices of both the Standard Model and the

Relational Supersymmetry via the Dressing Field Method and Matter‐Interaction Supergeometric Framework

Annalen der Physik, Volume 537, Issue 9, September 2025.
Applications of the Dressing Field Method are reviewed and further expanded to the very foundations of the supersymmetric framework, where it allows to build relational supersymmetric field theory. Furthermore, a novel approach is proposed giving a unified description of fermionic matter fields and bosonic gauge fields: a Matter‐Interaction ...

Abelian Hidden Sectors at a GeV [PDF]

, 2009
We discuss mechanisms for naturally generating GeV-scale hidden sectors in the context of weak-scale supersymmetry. Such low mass scales can arise when hidden sectors are more weakly coupled to supersymmetry breaking than the visible sector, as happens ...
