  Motivated by the null results of LHC searches, which together with the Higgs
mass, severely constrain minimal supersymmetric extensions of the standard
model, we adopt a model-independent approach to study charged slepton flavor.
We examine a number of simplified models, with different subsets of sleptons,
electroweak gauginos, and Higgsinos, and derive the allowed slepton flavor
dependence in the region probed by current LHC searches, and in the region
relevant for the 14 TeV LHC. We then study the impact of the allowed flavor
dependence on lepton plus missing energy searches. In some cases, flavor
dependence significantly modifies the reach of the searches. These effects may
be even larger at the next LHC run, since for the higher masses probed at 14
TeV, larger flavor mixings and relative mass splittings are compatible with
low-energy constraints. Retaining the full lepton flavor information can
increase the sensitivity of the searches.
