Higgs Mass and Unnatural Supersymmetry [PDF]

, 2014
Assuming that supersymmetry exists well above the weak scale, we derive the full one-loop matching conditions between the SM and the supersymmetric theory, allowing for the possibility of an intermediate Split-SUSY scale.

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.

Models of Little Higgs and Electroweak Precision Tests [PDF]

, 2006
The little Higgs idea is an alternative to supersymmetry as a solution to the gauge hierarchy problem. In this note, I review various little Higgs models and their phenomenology with emphases on the precision electroweak constraints in these models ...

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

Dark Dimension With (Little) Strings Attached

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Muon g − 2 vs LHC Run 2 in supersymmetric models

Journal of High Energy Physics, 2020
Supersymmetric models with sub-TeV charginos and sleptons have been a candidate for the origin of the long-standing discrepancy in the muon anomalous magnetic moment (g − 2). By gathering all the available LHC Run 2 results, we investigate the latest LHC

Foundations of Ghost Stability

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.
