 Efficiency of the CMS Drift Tubes at LHC in 2017 /CMS Collaboration The Hit and Segment Reconstruction efficiencies of Drift Tubes were studied on 2017 data. Summary plots and trend plots vs LHC Instantaneous Luminosity and Number of Reconstructed vertices (pileup) were obtained from a 13 /fb sample acquired in the second half of the year. Trend plots vs Run Number (time) were produced using the full 2017 sample.. CMS-DP-2018-016; CERN-CMS-DP-2018-016.- Geneva : CERN, 2018 - 28 p. Fulltext: PDF;

 Emittance scans for CMS luminosity calibration in 2017 /CMS Collaboration Emittance scans are short van der Meer type scans performed at the beginning and at the end of LHC fills. The beams are scanned against each other in X and Y planes in 7 displacement steps. [...] CMS-DP-2018-011; CERN-CMS-DP-2018-011.- Geneva : CERN, 2018 - 18 p. Fulltext: PDF;

 2017 Tau Trigger Efficiencies /CMS Collaboration Triggers selecting events with hadronically decaying $\tau$ leptons ($\tau_h$) are used in a wide variety of CMS analyses, in particular those targeting processes with a $H \rightarrow \tau\tau$ decay. The performance of the $\tau_h$ triggers is presented for data collected in 2017, corresponding to an integrated luminosity of 41.5\,fb$^{-1}$ at 13 TeV, and compared with simulation..

 Level-1 $\tau$ trigger performance in 2017 data /CMS Collaboration In 2017, the LHC achieved an instantaneous luminosity of 2.06x10$^{34}$cm$^{-2}$s$^{-1}$, and a peak average pile-up of more than 50. This document describes the performance of the CMS Level-1 calorimeter trigger for $\tau$ leptons using 40.9 fb$^{-1}$ of 2017 data.
