Closing in on the Wino LSP via trilepton searches at the LHC

Journal of High Energy Physics, 2018
The neutralino dark matter (DM) predicted by the Minimal Supersymmetric Standard Model (MSSM) has been probed in several search modes at the Large Hadron Collider (LHC), one of the leading ones among which is the trilepton plus missing transverse ...

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.

Chargino contributions in light of recent ϵ′/ϵ

Physics Letters B, 2016
Recently, the standard model prediction of ϵ′/ϵ was improved, and a discrepancy from the experimental results was reported at the 2.9σ level. We study the chargino contributions to Z penguin especially with the vacuum stability constraint.

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 ...

Search for nearly degenerate higgsinos via photon fusion with the semileptonic channel at the LHC

Nuclear Physics B
Electroweak scale higgsinos with a nearly degenerate spectrum in supersymmetric models are well-motivated, but generally less constrained at collider experiments as the decay products are often too soft to detect.
