Abstract: (arXiv)

We investigate a strategy to search for light, nearly degenerate higgsinos within the natural MSSM at the LHC. We demonstrate that the higgsino mass range

\mu

in

100-150

GeV, which is preferred by the naturalness, can be probed at

2\sigma

significance through the monojet search at 14 TeV HL-LHC with 3000 fb

^{-1}

luminosity. The proposed method can also probe certain region in the parameter space for the lightest neutralino with a high higgsino purity, that cannot be reached by planned direct detection experiments at XENON-1T(2017).
