Biνo phenomenology at the LHC

Abstract

Abstract We study 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 biνo. We consider a particle spectrum where the squarks are heavier than the lightest neutralino, which is a pure biνo. The biνo 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+ "Image missing" with $$ \sqrt{s}=13 $$ s = 13 TeV and $$ \mathrm{\mathcal{L}} $$ ℒ = 36 fb−1 of data to determine the constraints on the squark and biνo masses in this model. We find that squarks as light as 350 GeV are allowed if the biνo is lighter than 150 GeV and squarks heavier than 950 GeV are allowed for any biνo mass. We also present forecasts for the LHC with $$ \sqrt{s}=13 $$ s = 13 TeV and $$ \mathrm{\mathcal{L}} $$ ℒ = 300 fb−1 and show that squarks up to 1150 GeV can be probed.
