  The search for supersymmetry at Run 1 of LHC has resulted in gluino mass
limits m(gluino)>~ 1.3 TeV for the case where m(gluino)<<m(squark) and in
models with gaugino mass unification. The increased energy and ultimately
luminosity of LHC13 will explore the range m(gluino)~ 1.3-2 TeV. We examine how
the discovery of SUSY via gluino pair production would unfold via a comparative
analysis of three LSP archetype scenarios: 1. mSUGRA/CMSSM model with a
bino-like LSP, 2. charged SUSY breaking (CSB) with a wino-like LSP and 3. SUSY
with radiatively-driven naturalness (RNS) and a higgsino-like LSP. In all three
cases we expect heavy-to-very-heavy squarks as suggested by a decoupling
solution to the SUSY flavor and CP problems and by the gravitino problem. For
all cases, initial SUSY discovery would likely occur in the multi-b-jet +
ETMISS channel. The CSB scenario would be revealed by the presence of
highly-ionizing, terminating tracks from quasi-stable charginos. As further
data accrue, the RNS scenario with 100-200 GeV higgsino-like LSPs would be
revealed by the build-up of a mass edge/bump in the OS/SF dilepton invariant
mass which is bounded by the neutralino mass difference. The mSUGRA/CMSSM
archetype would contain neither of these features but would be revealed by a
buildup of the usual multi-lepton cascade decay signatures.
