Light and compressed gluinos at the LHC via string theory

European Physical Journal C: Particles and Fields, 2017
In this article, we show that making global fits of string theory model parameters to data is an interesting mechanism for probing, mapping and forecasting connections of the theory to real world physics.

Gauge Coupling Unification in Superstring Derived Standard--like Models

, 1993
I discuss gauge coupling unification in a class of superstring standard--like models, which are derived in the free fermionic formulation. Recent calculations indicate that the superstring unification scale is at $O(10^{18}GeV)$ while the minimal ...

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 ...

Two-Loop Renormalization Group Equations for Soft Supersymmetry-Breaking Couplings

, 2008
We compute the two-loop renormalization group equations for all soft supersymmetry-breaking couplings in a general softly broken N=1 supersymmetric model.

Anomaly induced inflation in the minimal quartic extension of Einstein’s gravity

European Physical Journal C: Particles and Fields
A 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 ...

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

Neutrino Masses within the Minimal Supersymmetric Standard Model

, 1992
We investigate the possibility of accommodating neutrino masses compatible with the MSW study of the Solar neutrino deficit within the minimal supersymmetric Standard Model.

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.

Radiative neutralino production in low energy supersymmetric Models. II. The case of beam polarization

, 2012
We study the production of the lightest neutralinos in the radiative process $e^+e^- \to \tilde\chi^0_1 \tilde\chi^0_1\gamma$ in low energy supersymmetric models for the International Linear Collider energies with longitudinally polarized electron and ...

Squark production with R-symmetry beyond NLO at the LHC

Journal of High Energy Physics
The 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.
