  Inspired by the latest measurement of muon g-2 by the Fermilab Experiment, we
revisit a class of supersymmetric models in which non-universality at M_GUT
allows us to realize relatively light sleptons in the few hundred GeV range.
These sleptons provide additional contributions to muon g-2 that can be
arranged to reconcile theory and experiment. The solutions compatible with the
muon g-2 resolution typically predict light sleptons, charginos and
neutralinos. We show how these solutions can be probed during LHC-Run3. A
direct impact on the chargino mass is observed such that the chargino can be
probed up to about 800 GeV during the Run3 experiments. Despite such a direct
impact, it is still possible to realize lighter chargino masses which can
escape detection due to the chirality mixture of the lighter slepton states.
The colored squarks as well as the gluino turn out to be heavier than about 3-4
TeV if the LSP neutralino satisfies the Planck bound on the dark matter relic
abundance. We highlight a variety of benchmark points and, in particular,
coannihilation scenarios with dark matter candidates that will be tested in the
ongoing and planned direct and indirect detection experiments. By relaxing the
requirement that the LSP neutralino saturates the relic dark matter abundance,
we are able to find solutions with gluino and squark masses in a range that may
be accessible at LHC-Run3.
