Pseudo-goldstino and electroweakinos via VBF processes at LHC

TL;DR

This paper investigates the production and decay of electroweakinos via VBF processes at the LHC within a SUSY framework predicting pseudo-goldstinos, highlighting potential observability at high luminosity.

Contribution

It introduces a study of electroweakino pair production via VBF processes involving pseudo-goldstinos, with detailed Monte Carlo simulations for LHC detection prospects.

Findings

Chargino+neutralino+2 jets channel can reach above 2-sigma significance at 14 TeV LHC with 3000 fb^{-1}.

Other production channels are not accessible with current sensitivity.

Pseudo-goldstino signatures could be observable in future collider experiments.

Abstract

The multi-sector SUSY breaking predicts pseudo-goldstino which can couple to the visible sector more strongly than the ordinary gavitino and thus induce the decays of the lightest neutralino and chargino (collectively called electroweakinos) inside the detector. In this note we study the electroweakino pair productions via vector boson fusion (VBF) processes followed by decays to pseudo-goldstino at the LHC. Our Monte Carlo simulations show that at the 14 TeV LHC with 3000 fb^{-1} luminosity the dominant production channel pp->chargino+neutralino+2 jets can have a statistical significance above 2-sigma while other production channels are not accessible.
