Searches for direct supersymmetric gaugino and slepton pair production in final states with leptons with the ATLAS detector

EPJ Web of Conferences, 2013
A search for direct production of supersymmetric gauginos and sleptons in final states with two and three leptons is presented. The two lepton analysis uses 4.7 fb−1 of proton-proton collision data at √s = 7 TeV, while the three lepton analysis uses 13 ...

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.

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.

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 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 ...

Implications of a stop sector signal at the LHC

Journal of High Energy Physics, 2018
Naturalness arguments suggest that the stop sector is within reach of the Large Hadron Collider (LHC). We investigate how the observation of a third generation squark signal could predict masses and discovery modes of other supersymmetric particles, or ...

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.

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.

Invisible dark matter decays of a non-Standard Model like CP-even scalar boson

Journal of King Saud University: Science
We investigate two extensions of the standard model that include particle dark matter candidates: the Next-to-Two Higgs Doublet Model and the Next-to-minimal Supersymmetric Standard Model.
