Searching for the Higgsino-Bino sector at the LHC

open access: yesJournal 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 ...

Gravitational waves from domain walls in the next-to-minimal supersymmetric standard model [PDF]

open access: yes, 2015
The next-to-minimal supersymmetric standard model predicts the formation of domain walls due to the spontaneous breaking of the discrete Z3-symmetry at the electroweak phase transition, and they collapse before the epoch of big bang nucleosynthesis if ...

The supersymmetric standard model [PDF]

open access: yesThe European Physical Journal C, 2014
The Standard Model may be included within a supersymmetric theory, postulating new sparticles that differ by half-a-unit of spin from their standard model partners, and by a new quantum number called R-parity. The lightest one, usually a neutralino, is expected to be stable and a possible candidate for dark matter. The electroweak breaking requires two

Probing compressed dark sectors at 100 TeV in the dileptonic mono-Z channel

open access: yesJournal 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.

Minimal non-abelian supersymmetric Twin Higgs

open access: yesJournal 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

open access: yesJournal 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.

Z(2)-Singlino Dark Matter in a Portal-Like Extension of the Minimal Supersymmetric Standard Model. [PDF]

open access: yes, 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 ...

Muon g−2 and dark matter in the minimal supersymmetric standard model

open access: yesPhysical Review D, 2018
We investigate the possibility that both dark matter and the long-standing discrepancy in the anomalous magnetic moment of the muon may be explained within the MSSM. In light of the stringent bounds from direct detection, we argue that the most promising

Indirect probe of electroweakly interacting particles at the high-luminosity Large Hadron Collider

open access: yesJournal 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.
