Searching for the Higgsino-Bino sector at the LHC
Journal of High Energy Physics, 2020 We study the search for electroweakinos at the 13 TeV LHC in the case of heavy scalar superpartners. We consider both the direct production mode and the one associated with the decay of heavy Higgs bosons, and concentrate on the case of light Higgsinos ...

Z(2)-Singlino Dark Matter in a Portal-Like Extension of the Minimal Supersymmetric Standard Model. [PDF]
, 2008 We propose a Z2-stabilized singlino () as a dark matter candidate in extended and R-parity violating versions of the supersymmetric standard model. interacts with visible matter via a heavy messenger field S, which results in a supersymmetric version of ...

Probing compressed dark sectors at 100 TeV in the dileptonic mono-Z channel
Journal of High Energy Physics, 2018 We examine the sensitivity at a future 100 TeV proton-proton collider to compressed dark sectors whose decay products are invisible due to below-threshold energies and/or small couplings to the Standard Model.

New physics explanations of a μ in light of the FNAL muon g − 2 measurement
Journal of High Energy Physics, 2021 The Fermilab Muon g −2 experiment recently reported its first measurement of the anomalous magnetic moment a μ FNAL $$ {a}_{\mu}^{\mathrm{FNAL}} $$ , which is in full agreement with the previous BNL measurement and pushes the world average deviation ∆ a ...

Renormalization of the Minimal Supersymmetric Standard Model [PDF]
, 2002 The renormalization of the Minimal Supersymmetric Standard Model (MSSM) is presented. We describe symmetry identities that constitute a framework in which the MSSM is completely characterized and renormalizability can be proven.

Minimal non-abelian supersymmetric Twin Higgs
Journal of High Energy Physics, 2017 We propose a minimal supersymmetric Twin Higgs model that can accommodate tuning of the electroweak scale for heavy stops better than 10% with high mediation scales of supersymmetry breaking.

Displaced vertex signatures of a pseudo-Goldstone sterile neutrino
Journal of High Energy Physics, 2021 Low-scale models of neutrino mass generation often feature sterile neutrinos with masses in the GeV-TeV range, which can be produced at colliders through their mixing with the Standard Model neutrinos.

Least supersymmetric standard model
Physical Review D, 2012 We propose the minimal (least) version of the supersymmetric standard model which can solve the hierarchy problem in the same way as the so-called minimal supersymmetric standard model and presents solutions to some of its problems. Supersymmetry is broken in a secluded sector and mediated to the observable sector by messengers of a gauge group $G ...

Indirect probe of electroweakly interacting particles at the high-luminosity Large Hadron Collider
Journal of High Energy Physics, 2018 Many extensions of the standard model (SM) involve new massive particles charged under the electroweak gauge symmetry. The electroweakly interacting new particles affect various SM processes through radiative corrections.

Impact of an extra gauge interaction on naturalness of supersymmetry
Journal of High Energy Physics, 2018 It is pointed out that in supersymmetric models with a new gauge symmetry under which the Higgs is charged, the fine-tuning of the electroweak symmetry breaking is relaxed due to suppression of the top Yukawa coupling at higher scales by a new large ...
