Squark/gluino searches in leptonic channels with the CMS experiment

The second run of the LHC at the increased centre-of-mass energy of 13 TeV significantly extends the sensitivity to possible models of supersymmetry; the largest increase in cross section isexpected for heavy gluino and squark pair production. Leptonic final states provide a complementary method to all-hadronic inclusive searches, while also allowing to explore more complicatedSUSY scenarios. Several searches performed at the CMS experiment using the 2015 data with an integrated luminosity of 2.3 fb$^{-1}$ are presented. The results are interpreted within the framework of simplified models, and allow to impose limits on a large variety of signal scenarios
