Muon Identification and Isolation efficiency on full 2016 dataset /CMS Collaboration
The performance of muon reconstruction and identification in CMS has been studied on data collected in pp collisions at $\sqrt{s}$ = 13 TeV at the LHC. It has been studied on a sample of muons corresponding to an integrated luminosity of up to 36 $fb^{-1}$. [...]

Performance of tau identification with 2016 data at $\sqrt{s}$ = 13 TeV /CMS Collaboration
The document presents the performance of the CMS hadrons-plus-strips (HPS) algorithm, used to reconstruct $\tau$ leptons in their hadronic decays, evaluated with proton-proton collision data recorded in 2016 at $\sqrt{s}$ = 13 TeV. The measurements are performed for $\tau_{h}$ identification efficiency, $\tau_{h}$ energy scale, and the probability of electrons or muons mis-identified as hadronic $\tau$ decays..

Heavy flavor identification at CMS with deep neural networks /CMS Collaboration
At the Large Hadron Collider, the identification of jets originating from heavy flavour quarks (b or c-tagging) is important for searches for new physics and for measurements of standard model processes. A variety of b-tagging algorithms has been developed by CMS to select b-quark jets based on variables such as the impact parameters of the charged-particle tracks, the properties of reconstructed decay vertices, and the presence or absence of a lepton, or combinations thereof.
