Search for direct top squark pair production in final states with one isolated lepton using 21 fb−1 of data collected with the ATLAS detector

EPJ Web of Conferences, 2014
Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the third generation quarks with masses not too far from those of their Standard Model counterparts. Top or bottom scalar quarks (or squarks) with masses less than a few

The effect of supersymmetric CP phases on Chargino-Pair Production via Drell-Yan Process at the LHC

, 2004
We compute the rates for pp annihilation into chargino-pairs via Drell-Yan process taking into account the effects of supersymmetric soft phases, at proton-proton collider.

Chargino contribution to the rare decay b→ss

Physics Letters B, 2004
AbstractThe rare decay b→ssd̄ is studied in the supersymmetric Standard Model by considering the contribution from the chargino box diagrams. We find that this contribution amounts to 10−9 in the branching ratio.

Probing compressed mass spectrum supersymmetry at the high-luminosity LHC with the vector boson fusion topology

European Physical Journal C: Particles and Fields
We present a phenomenology study investigating pair production of supersymmetric charginos and neutralinos (“electroweakinos”) with the vector boson fusion (VBF) topology in proton-proton collisions at CERN’s Large Hadron Collider (LHC).

Inclusive searches for SUSY from CMS

EPJ Web of Conferences, 2014
Many searches for supersymmetry have been performed by the CMS collaboration at the LHC and in this document a selection of results of inclusive searches is presented.

Search for new phenomena in final states with two opposite-charge, same-flavor leptons, jets, and missing transverse momentum in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

Journal of High Energy Physics, 2018
Search results are presented for physics beyond the standard model in final states with two opposite-charge, same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton

Natural SUSY at LHC with Right-Sneutrino LSP

, 2018
We study an extension of the minimal supersymmetric standard model (MSSM) with additional right-handed singlet neutrino superfields. While such an extension incorporates a mechanism for the neutrino mass, it also opens up the possibility of having the ...

Searching for supersymmetry in Z’ decays

EPJ Web of Conferences, 2013
I investigate production and decay of heavy neutral gauge bosons Z’ in GUT-inspired U(1)’ groups and in the Sequential Standard Model. In particular, decays into supersymmetric particles, such as slepton, chargino and neutralino pairs, as predicted in ...

Stop Decay with LSP Gravitino in the final state: $\tilde{t}_1\to\widetilde{G}\,W\,b$

, 2016
In MSSM scenarios where the gravitino is the lightest supersymmetric particle (LSP), and therefore a viable dark matter candidate, the stop $\tilde{t}_1$ could be the next-to-lightest superpartner (NLSP). For a mass spectrum satisfying: $m_{\widetilde{G}}
