 The CMS Phase-1 pixel detector -- experience and lessons learned from two years of operation / Vormwald, Benedikt Roland (Hamburg U.) /CMS Collaboration In 2017, CMS has installed a new pixel detector with 124M channels that features full 4-hit coverage in the tracking volume ($\eta<2.5$) and is capable to withstand instantaneous luminosities of $2\cdot10^{34}\,\mathrm{cm}^{-2}\mathrm{s}^{-1}$ and beyond. By now the detector has been successfully operated for two years in proton and heavy ion collisions. [...] CMS-CR-2019-019.- Geneva : CERN, 2019 - 11 p.

 Results and prospects with the CMS-TOTEM Precision Proton Spectrometer / Vilela Pereira, Antonio (Rio de Janeiro State U.) /CMS and TOTEM Collaborations The PPS (Precision Proton Spectrometer) detector system consists of silicon tracking stations as well as timing detectors to measure both the position and direction of protons and their time-of-flight with high precision. They are located at around 200--220~m from the interaction point in the very forward region on both sides of the CMS experiment. [...] CMS-CR-2019-096.- Geneva : CERN, 2019 - 7 p.
