Supersymmetry is a popular extension to the standard model, which may solve the hierarchy problem without fine-tuning if it introduces top and bottom squarks with masses not larger than several hundred GeV. This note describes three searches for the direct pair production of these particles, based on a sample of pp collisions data corresponding to approximately 10 fb-1 collected by the Compact Muon Solenoid detector at the LHC, at a center-of-mass energy √s = 8 TeV. The searches are performed in the single lepton final state focusing on events with large transverse mass, the same-sign dilepton final state, and the all-hadronic final state using the αT quantity. No evidence for the production of top or bottom squarks is observed. The results are used to place stringent constraints on the masses of these particles.
