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.

Flavor in SU(5)$SU(5)$ Finite Grand Unified Models
Fortschritte der Physik, Volume 72, Issue 12, December 2024.Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Constraining compressed versions of MUED and MSSM using soft tracks at the LHC
Journal of High Energy Physics, 2017 A compressed spectrum is an anticipated hideout for many beyond standard model scenarios. Such a spectrum naturally arises in the minimal universal extra dimension framework and also in supersymmetric scenarios.

Constraining sleptons at the LHC in a supersymmetric low-scale seesaw scenario
European Physical Journal C: Particles and Fields, 2017 We consider a scenario inspired by natural supersymmetry, where neutrino data is explained within a low-scale seesaw scenario. We extend the Minimal Supersymmetric Standard Model by adding light right-handed neutrinos and their superpartners, the R ...

Supersymmetric naturalness beyond MSSM
Journal of High Energy Physics, 2019 The experiments at the Large Hadron Collider (LHC) have pushed the limits on masses of supersymmetric particles beyond the ∼TeV scale. This compromises naturalness of the simplest supersymmetric extension of the Standard Model, the minimal supersymmetric

Anomaly induced inflation in the minimal quartic extension of Einstein’s gravity
European Physical Journal C: Particles and FieldsA particular extension of Einstein’s General Relativity up to and including quartic terms in the curvature tensor is minimal in the sense that it has a unique maximally symmetric vacuum and only a massless spin-2 excitation in its spectrum around the ...

Reduction of the parameters in MSSM
Journal of High Energy Physics, 2018 In the present work we search for renormalization group invariant relations among the various massless and massive parameters of the Minimal Supersymmetric Standard Model.

Squark production with R-symmetry beyond NLO at the LHC
Journal of High Energy PhysicsThe Minimal R-symmetric Supersymmetric Standard Model (MRSSM) provides a realisation of supersymmetry in which the parameter space is less constrained by the current LHC data than in the simplest supersymmetric scenarios.
