Abstract: Results of searches for heavy stablecharged particles produced in pp collisions at $\sqrt{s} = 7$ and 8 TeV are presented. Data collected with the CMS detector are used to study the momentum, energy deposition, and time-of-flight of candidate events. Fermions with an electric charge of $e$/3 to 5$e$ as well as bound states suffering from charge flipping (charged to/from neutral) are studied. Analysis results are presented for various combinations of signatures in the inner tracker only, inner tracker plus muon system, and muon system only. Detector signatures under study are long time-of-flight to the outer muon system and anomalously high (or low) energy deposition in the inner tracker. The data are consistent with the expected background and limits on the cross section for production of long-lived scalar taus, scalar tops and gluinos, as well as direct pair production of lepton-like long-lived fermions are set.
