Muon Isolation for Heavy Stop Decays

The search for high mass stops will play an important role in the future due to the increase of the LHC center-of-mass energy to $14$ TeV. High stop masses lead to heavily boosted decay products. Because of the high boost the lepton isolation which is applied in the standard selection often removes $\mu$ from $W$-boson decays. Different approaches to recover these non-isolated muons are reviewed and their advantages and disadvantages are discussed.
