New bounds on light sneutrino masses: Rare SUSY signals

We study bounds on a neutral component of weak doublet scalar lepton. A typical example such particle is sneutrinos in supersymmetric models. Using constraints from invisible Higgs decays we place lower bound approximately $m_h/2$. recast mono-$W/Z$ search, with hadronic vector boson tag order to parameter space the sneutrino--charged slepton mass plane. find range 55-100 GeV 36 $\text{fb}^{-1}$ data set depending charged component. propose sensitivity search channel for HL-LHC and discuss both discovery potential case an excess seen exclusion limit assuming no seen.
