Performance of quark/gluon discrimination in 13 TeV data /CMS Collaboration
The 2015 proton collision data at 13 TeV and corresponding simulated samples are used to produce an updated quark/gluon jet discriminator and to validate its performances making use of dimuon plus jet and dijet selected events. The three input discriminating jet observables are the same as those used for the latest validated Run 1 discriminator, as well as the likelihood method to combine them. [...]

RPC Overall Efficiency Measurement from Tracker Muons /CMS Collaboration
From the Run-II, the RPCMuon reconstruction algorithm is included in the standard reconstruction, where the algorithm starts from the inner track and finds matched RPC hits(RPCRecHits) along its trajectory. The track extrapolation is done in this step and the results of extrapolation are stored in the muon objects. [...]

Data/MC Comparison for ECAL and HCAL /CMS Collaboration
CMS has tuned its simulation program and chosen a specific physics model of Geant4 by comparing the simulation results with dedicated test beam experiments. CMS continues to validate the physics models inside Geant4 using the test beam data as well as collision data. [...]

Performance of muon reconstruction including Alignment Position Errors for 2016 Collision Data /CMS Collaboration
From 2016 Run muon reconstruction is using non-zero Alignment Position Errors to account for the residual uncertainties of muon chambers' positions. Significant improvements are obtained in particular for the startup phase after opening/closing the muon detector. [...]

Expected tau identification performance in LHC run-2 at $\sqrt{s}$ = 13 TeV /CMS Collaboration
This document provides the expected performance of the run-2 tau identification algorithm using an inclusive definition of $\tau_{h}$ reconstruction and identification efficiency and jet $\rightarrow$ $\tau_{h}$ mis-identification probability. The materials presented in this article are useful for phenomenological studies..

CMS Tracker Alignment Performance Results Summer 2016 /CMS Collaboration
The tracking system of the CMS detector provides excellent resolution for charged particle tracks and an efficient way of tagging jets. In order to reconstruct good quality tracks, the position and orientation of each silicon pixel and strip modules need to be determined with a precision of several micrometers. [...]
