Geometric Relational Framework for General‐Relativistic Gauge Field Theories
Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract It is recalled how relationality arises as the core insight of general‐relativistic gauge field theories from the articulation of the generalized hole and point‐coincidence arguments. Hence, a compelling case for a manifestly relational framework ensues naturally.

Impact of vacuum stability constraints on the phenomenology of supersymmetric models
Journal of High Energy Physics, 2019 We present a fast and efficient method for studying vacuum stability constraints in multi-scalar theories beyond the Standard Model. This method is designed for a reliable use in large scale parameter scans.

About R-parity and the Supersymmetric Standard Model
, 1999 We recall the obstacles which seemed, long ago, to prevent one from viewing supersymmetry as a possible fundamental symmetry of Nature. Is spontaneous supersymmetry breaking possible ?

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

Simultaneous search for extra light and heavy Higgs bosons via cascade decays
Journal of High Energy Physics, 2017 Models with extended Higgs sectors can contain several additional Higgs states, heavier or lighter than the SM Higgs boson. The couplings of lighter extra states to SM particles can be strongly reduced, leading to small cross sections for their direct ...

Pseudoscalar Field as a Possible Candidate for Phantom Field
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We demonstrate the existence of a single pseudoscalar (PS) field in the mathematically backed and parity‐preserving modifications of the standard Stückelberg formalism (SSF) in the context of the Lagrangian formulation of the (i) two (1 + 1)‐dimensional (2D) massive Abelian 1‐form gauge theory, (ii) three (2 + 1)‐dimensional (3D) massive Abelian 2‐form

Journal of High Energy Physics, 2019 In Higgs portal models of fermion dark matter, scalar couplings are unavoidably suppressed by strong bounds from direct detection experiments. As a consequence, thermal dark matter relics must coexist with mediators in a compressed spectrum of dark ...

Interplay Between MW, ΩCDMh2, and (g − 2)μ in Flavor Symmetry–Based Supersymmetric Models
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We study the phenomenological implications of the minimal supersymmetric standard model (MSSM) augmented by a nonabelian flavor symmetry labeled as sMSSM. Incorporating this flavor symmetry allows for a significant reduction in the original plethora of free parameters present in the MSSM, ultimately reducing them down to just seven in sMSSM.
