Title: Biνo phenomenology at the LHC

Abstract

We observe the LHC constraints on an $R$-symmetric SUSY model, where the neutrino masses are generated through higher dimensional operators involving the pseudo-Dirac bino, named bi$$\nu$$o. We consider a particle spectrum where the squarks are heavier than the lightest neutralino, which is a pure bi$$\nu$$o. The bi$$\nu$$o is produced through squark decays and it subsequently decays to a combination of jets and leptons, with or without missing energy, via its mixing with the Standard Model neutrinos. We recast the most recent LHC searches for jets+missing energy with $$\sqrt{s}=13~$$TeV and $$\mathcal{L}=36~{\rm fb}^{-1}$$ of data to determine the constraints on the squark and bi$$\nu$$o masses in this model. We find that squarks as light as 350 GeV are allowed if the bi$$\nu$$o is lighter than 150 GeV and squarks heavier than 950 GeV are allowed for any bi$$\nu$$o mass. We also present forecasts for the LHC with $$\sqrt{s}=13$$ TeV and $$\mathcal{L}=300~{\rm fb}^{-1}$$ and show that squarks up to 1150 GeV can be probed.
