Query: Top-squark in natural SUSY under current LHC run-2 data   We utilize the recent LHC-13 TeV data to study the lower mass bound on
top-squark (stop) in natural supersymmetry. We recast the LHC sparticle
inclusive search of $(\ge 1){\rm jets} + E^{miss}_T$ with $\alpha_T$ variable,
the direct stop pair search (1-lepton channel and all-hadronic channel) and the
monojet analyses. We find that these searches are complementary depending on
stop and higgsino masses: for a heavy stop the all-hadronic stop pair search
provides the strongest bound, for an intermediate stop the inclusive SUSY
analysis with $\alpha_T$ variable is most efficient, while for a compressed
stop-higgsino scenario the monojet search plays the key role. Finally, the
lower mass bound on a stop is: (i) 320 GeV for compressed stop-higgsino
scenario (mass splitting less than 20 GeV); (ii) 765 (860) GeV for higgsinos
lighter than 300 (100) GeV.
