Search for Top and Bottom squarks at CMS

Supersymmetry is a popular extension to the standard problem, which may solve the hierarchy problem without fine-tuning if it introduces top and bottom squarks with masses not more than several hundred GeV. This note describes three searches for the direct pair production of these particles, which 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 alphaT 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.
